# Introduction [PDF Generator API](https://pdfgeneratorapi.com) allows you easily generate transactional PDF documents and reduce the development and support costs by enabling your users to create and manage their document templates using a browser-based drag-and-drop document editor. The PDF Generator API features a web API architecture, allowing you to code in the language of your choice. This API supports the JSON media type, and uses UTF-8 character encoding. ## Base URL The base URL for all the API endpoints is `https://us1.pdfgeneratorapi.com/api/v4` For example * `https://us1.pdfgeneratorapi.com/api/v4/templates` * `https://us1.pdfgeneratorapi.com/api/v4/workspaces` * `https://us1.pdfgeneratorapi.com/api/v4/templates/123123` ## Editor PDF Generator API comes with a powerful drag & drop editor that allows to create any kind of document templates, from barcode labels to invoices, quotes and reports. You can find tutorials and videos from our [Support Portal](https://support.pdfgeneratorapi.com). * [Component specification](https://support.pdfgeneratorapi.com/en/category/components-1ffseaj/) * [Expression Language documentation](https://support.pdfgeneratorapi.com/en/category/expression-language-q203pa/) * [Frequently asked questions and answers](https://support.pdfgeneratorapi.com/en/category/qanda-1ov519d/) ## Definitions ### Organization Organization is a group of workspaces owned by your account. ### Workspace Workspace contains templates. Each workspace has access to their own templates and organization default templates. ### Master Workspace Master Workspace is the main/default workspace of your Organization. The Master Workspace identifier is the email you signed up with. ### Default Template Default template is a template that is available for all workspaces by default. You can set the template access type under Page Setup. If template has "Organization" access then your users can use them from the "New" menu in the Editor. ### Data Field Data Field is a placeholder for the specific data in your JSON data set. In this example JSON you can access the buyer name using Data Field `{paymentDetails::buyerName}`. The separator between depth levels is :: (two colons). When designing the template you don’t have to know every Data Field, our editor automatically extracts all the available fields from your data set and provides an easy way to insert them into the template. ``` { "documentNumber": 1, "paymentDetails": { "method": "Credit Card", "buyerName": "John Smith" }, "items": [ { "id": 1, "name": "Item one" } ] } ``` ## Rate limiting Our API endpoints use IP-based rate limiting and allow you to make up to 2 requests per second and 60 requests per minute. If you make more requests, you will receive a response with HTTP code 429. Response headers contain additional values: | Header | Description | |--------|--------------------------------| | X-RateLimit-Limit | Maximum requests per minute | | X-RateLimit-Remaining | The requests remaining in the current minute | | Retry-After | How many seconds you need to wait until you are allowed to make requests | * * * * * # Libraries and SDKs ## Postman Collection We have created a [Postman Collection](https://www.postman.com/pdfgeneratorapi/workspace/pdf-generator-api-public-workspace/overview) so you can easily test all the API endpoints without developing and code. You can download the collection [here](https://www.postman.com/pdfgeneratorapi/workspace/pdf-generator-api-public-workspace/collection/11578263-42fed446-af7e-4266-84e1-69e8c1752e93). ## Client Libraries All our Client Libraries are auto-generated using [OpenAPI Generator](https://openapi-generator.tech/) which uses the OpenAPI v3 specification to automatically generate a client library in specific programming language. * [PHP Client](https://github.com/pdfgeneratorapi/php-client) * [Java Client](https://github.com/pdfgeneratorapi/java-client) * [Ruby Client](https://github.com/pdfgeneratorapi/ruby-client) * [Python Client](https://github.com/pdfgeneratorapi/python-client) * [Javascript Client](https://github.com/pdfgeneratorapi/javascript-client) We have validated the generated libraries, but let us know if you find any anomalies in the client code. * * * * * # Authentication The PDF Generator API uses __JSON Web Tokens (JWT)__ to authenticate all API requests. These tokens offer a method to establish secure server-to-server authentication by transferring a compact JSON object with a signed payload of your account’s API Key and Secret. When authenticating to the PDF Generator API, a JWT should be generated uniquely by a __server-side application__ and included as a __Bearer Token__ in the header of each request. ## Accessing your API Key and Secret You can find your __API Key__ and __API Secret__ from the __Account Settings__ page after you login to PDF Generator API [here](https://pdfgeneratorapi.com/login). ## Creating a JWT JSON Web Tokens are composed of three sections: a header, a payload (containing a claim set), and a signature. The header and payload are JSON objects, which are serialized to UTF-8 bytes, then encoded using base64url encoding. The JWT's header, payload, and signature are concatenated with periods (.). As a result, a JWT typically takes the following form: ``` {Base64url encoded header}.{Base64url encoded payload}.{Base64url encoded signature} ``` We recommend and support libraries provided on [jwt.io](https://jwt.io/). While other libraries can create JWT, these recommended libraries are the most robust. ### Header Property `alg` defines which signing algorithm is being used. PDF Generator API users HS256. Property `typ` defines the type of token and it is always JWT. ``` { "alg": "HS256", "typ": "JWT" } ``` ### Payload The second part of the token is the payload, which contains the claims or the pieces of information being passed about the user and any metadata required. It is mandatory to specify the following claims: * issuer (`iss`): Your API key * subject (`sub`): Workspace identifier * expiration time (`exp`): Timestamp (unix epoch time) until the token is valid. It is highly recommended to set the exp timestamp for a short period, i.e. a matter of seconds. This way, if a token is intercepted or shared, the token will only be valid for a short period of time. ``` { "iss": "ad54aaff89ffdfeff178bb8a8f359b29fcb20edb56250b9f584aa2cb0162ed4a", "sub": "[email protected]", "exp": 1586112639 } ``` ### Payload for Partners Our partners can send their unique identifier (provided by us) in JWT's partner_id claim. If the `partner_id` value is specified in the JWT, the organization making the request is automatically connected to the partner account. * Partner ID (`partner_id`): Unique identifier provide by PDF Generator API team ``` { "iss": "ad54aaff89ffdfeff178bb8a8f359b29fcb20edb56250b9f584aa2cb0162ed4a", "sub": "[email protected]", "partner_id": "my-partner-identifier", "exp": 1586112639 } ``` ### Signature To create the signature part you have to take the encoded header, the encoded payload, a secret, the algorithm specified in the header, and sign that. The signature is used to verify the message wasn't changed along the way, and, in the case of tokens signed with a private key, it can also verify that the sender of the JWT is who it says it is. ``` HMACSHA256( base64UrlEncode(header) + "." + base64UrlEncode(payload), API_SECRET) ``` ### Putting all together The output is three Base64-URL strings separated by dots. The following shows a JWT that has the previous header and payload encoded, and it is signed with a secret. ``` eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJhZDU0YWFmZjg5ZmZkZmVmZjE3OGJiOGE4ZjM1OWIyOWZjYjIwZWRiNTYyNTBiOWY1ODRhYTJjYjAxNjJlZDRhIiwic3ViIjoiZGVtby5leGFtcGxlQGFjdHVhbHJlcG9ydHMuY29tIn0.SxO-H7UYYYsclS8RGWO1qf0z1cB1m73wF9FLl9RCc1Q // Base64 encoded header: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9 // Base64 encoded payload: eyJpc3MiOiJhZDU0YWFmZjg5ZmZkZmVmZjE3OGJiOGE4ZjM1OWIyOWZjYjIwZWRiNTYyNTBiOWY1ODRhYTJjYjAxNjJlZDRhIiwic3ViIjoiZGVtby5leGFtcGxlQGFjdHVhbHJlcG9ydHMuY29tIn0 // Signature: SxO-H7UYYYsclS8RGWO1qf0z1cB1m73wF9FLl9RCc1Q ``` ## Temporary JWTs You can create a temporary token in [Account Settings](https://pdfgeneratorapi.com/account/organization) page after you login to PDF Generator API. The generated token uses your email address as the subject (`sub`) value and is valid for __15 minutes__. You can also use [jwt.io](https://jwt.io/) to generate test tokens for your API calls. These test tokens should never be used in production applications. * * * * * # Error codes | Code | Description | |--------|--------------------------------| | 401 | Unauthorized | | 402 | Payment Required | | 403 | Forbidden | | 404 | Not Found | | 422 | Unprocessable Entity | | 429 | Too Many Requests | | 500 | Internal Server Error | ## 401 Unauthorized | Description | |-------------------------------------------------------------------------| | Authentication failed: request expired | | Authentication failed: workspace missing | | Authentication failed: key missing | | Authentication failed: property 'iss' (issuer) missing in JWT | | Authentication failed: property 'sub' (subject) missing in JWT | | Authentication failed: property 'exp' (expiration time) missing in JWT | | Authentication failed: incorrect signature | ## 402 Payment Required | Description | |-------------------------------------------------------------------------| | Your account is suspended, please upgrade your account | ## 403 Forbidden | Description | |-------------------------------------------------------------------------| | Your account has exceeded the monthly document generation limit. | | Access not granted: You cannot delete master workspace via API | | Access not granted: Template is not accessible by this organization | | Your session has expired, please close and reopen the editor. | ## 404 Entity not found | Description | |-------------------------------------------------------------------------| | Entity not found | | Resource not found | | None of the templates is available for the workspace. | ## 422 Unprocessable Entity | Description | |-------------------------------------------------------------------------| | Unable to parse JSON, please check formatting | | Required parameter missing | | Required parameter missing: template definition not defined | | Required parameter missing: template not defined | ## 429 Too Many Requests | Description | |-------------------------------------------------------------------------| | You can make up to 2 requests per second and 60 requests per minute. | * * * * *

# Introduction SendPost provides email API and SMTP relay which can be used not just to send & measure but also alert & optimised email sending. You can use SendPost to: * Send personalised emails to multiple recipients using email API * Track opens and clicks * Analyse statistics around open, clicks, bounce, unsubscribe and spam At and advanced level you can use it to: * Manage multiple sub-accounts which may map to your promotional or transactional sending, multiple product lines or multiple customers * Classify your emails using groups for better analysis * Analyse and fix email sending at sub-account level, IP Pool level or group level * Have automated alerts to notify disruptions regarding email sending * Manage different dedicated IP Pools so to better control your email sending * Automatically know when IP or domain is blacklisted or sender score is down * Leverage pro deliverability tools to get significantly better email deliverability & inboxing [](https://god.gw.postman.com/run-collection/33476323-e6dbd27f-c4a7-4d49-bcac-94b0611b938b?action=collection%2Ffork&source=rip_markdown&collection-url=entityId%3D33476323-e6dbd27f-c4a7-4d49-bcac-94b0611b938b%26entityType%3Dcollection%26workspaceId%3D6b1e4f65-96a9-4136-9512-6266c852517e) # Overview ## REST API SendPost API is built on REST API principles. Authenticated users can interact with any of the API endpoints to perform: * **GET**- to get a resource * **POST** - to create a resource * **PUT** - to update an existing resource * **DELETE** - to delete a resource The API endpoint for all API calls is: https://api.sendpost.io/api/v1 Some conventions that have been followed in the API design overall are following: * All resources have either /api/v1/subaccount or /api/v1/account in their API call resource path based on who is authorised for the resource. All API calls with path /api/v1/subaccount use X-SubAccount-ApiKey in their request header. Likewise all API calls with path /api/v1/account use X-Account-ApiKey in their request header. * All resource endpoints end with singular name and not plural. So we have domain instead of domains for domain resource endpoint. Likewise we have sender instead of senders for sender resource endpoint. * Body submitted for POST / PUT API calls as well as JSON response from SendPost API follow camelcase convention * All timestamps returned in response (created or submittedAt response fields) are UNIX nano epoch timestamp. All resources have either /api/v1/subaccount or /api/v1/account in their API call resource path based on who is authorised for the resource. All API calls with path /api/v1/subaccount use X-SubAccount-ApiKey in their request header. Likewise all API calls with path /api/v1/account use X-Account-ApiKey in their request header. SendPost uses conventional HTTP response codes to indicate the success or failure of an API request. * Codes in the 2xx range indicate success. * Codes in the 4xx range indicate an error owing due to unauthorize access, incorrect request parameters or body etc. * Code in the 5xx range indicate an eror with SendPost's servers ( internal service issue or maintenance ) SendPost all responses return created in UNIX nano epoch timestamp. ## Authentication SendPost uses API keys for authentication. You can register a new SendPost API key at our [developer portal](https://app.sendpost.io/register). SendPost expects the API key to be included in all API requests to the server in a header that looks like the following: `X-SubAccount-ApiKey: AHEZEP8192SEGH` This API key is used for all Sub-Account level operations such as: * Sending emails * Retrieving stats regarding open, click, bounce, unsubscribe and spam * Uploading suppressions list * Verifying sending domains and more In addition to X-SubAccount-ApiKey you also have another API Key X-Account-APIKey which is used for Account level operations such as : * Creating and managing sub-accounts * Allocating IPs for your account * Getting overall billing and usage information * Email List validation * Creating and managing alerts and more You must look at individual API reference page to look at whether X-SubAccount-ApiKey is required or X-Account-ApiKey In case an incorrect API Key header is specified or if it is missed you will get HTTP Response 401 ( Unauthorized ) response from SendPost. ## HTTP Response Headers Code | Reason | Details ---------------| -----------------------| ----------- 200 | Success | Everything went well 401 | Unauthorized | Incorrect or missing API header either X-SubAccount-ApiKey or X-Account-ApiKey 403 | Forbidden | Typically sent when resource with same name or details already exist 406 | Missing resource id | Resource id specified is either missing or doesn't exist 422 | Unprocessable entity | Request body is not in proper format 500 | Internal server error | Some error happened at SendPost while processing API request 503 | Service Unavailable | SendPost is offline for maintenance. Please try again later # API SDKs We have native SendPost SDKs in the following programming languages. You can integrate with them or create your own SDK with our API specification. In case you need any assistance with respect to API then do reachout to our team from website chat or email us at **[email protected]** * [PHP](https://github.com/sendpost/sendpost_php_sdk) * [Javascript](https://github.com/sendpost/sendpost_javascript_sdk) * [Ruby](https://github.com/sendpost/sendpost_ruby_sdk) * [Python](https://github.com/sendpost/sendpost_python_sdk) * [Golang](https://github.com/sendpost/sendpost_go_sdk) # API Reference SendX REST API can be broken down into two major sub-sections: * Sub-Account * Account Sub-Account API operations enable common email sending API use-cases like sending bulk email, adding new domains or senders for email sending programmatically, retrieving stats, adding suppressions etc. All Sub-Account API operations need to pass X-SubAccount-ApiKey header with every API call. The Account API operations allow users to manage multiple sub-accounts and manage IPs. A single parent SendPost account can have 100's of sub-accounts. You may want to create sub-accounts for different products your company is running or to segregate types of emails or for managing email sending across multiple customers of yours. # SMTP Reference Simple Mail Transfer Protocol (SMTP) is a quick and easy way to send email from one server to another. SendPost provides an SMTP service that allows you to deliver your email via our servers instead of your own client or server. This means you can count on SendPost's delivery at scale for your SMTP needs. ## Integrating SMTP 1. Get the SMTP `username` and `password` from your SendPost account. 2. Set the server host in your email client or application to `smtp.sendpost.io`. This setting is sometimes referred to as the external SMTP server or the SMTP relay. 3. Set the `username` and `password`. 4. Set the port to `587` (or as specified below). ## SMTP Ports - For an unencrypted or a TLS connection, use port `25`, `2525` or `587`. - For a SSL connection, use port `465` - Check your firewall and network to ensure they're not blocking any of our SMTP Endpoints. SendPost supports STARTTLS for establishing a TLS-encrypted connection. STARTTLS is a means of upgrading an unencrypted connection to an encrypted connection. There are versions of STARTTLS for a variety of protocols; the SMTP version is defined in [RFC 3207](https://www.ietf.org/rfc/rfc3207.txt). To set up a STARTTLS connection, the SMTP client connects to the SendPost SMTP endpoint `smtp.sendpost.io` on port 25, 587, or 2525, issues an EHLO command, and waits for the server to announce that it supports the STARTTLS SMTP extension. The client then issues the STARTTLS command, initiating TLS negotiation. When negotiation is complete, the client issues an EHLO command over the new encrypted connection, and the SMTP session proceeds normally. If you are unsure which port to use, a TLS connection on port 587 is typically recommended. ## Sending email from your application ```javascript "use strict"; const nodemailer = require("nodemailer"); async function main() { // create reusable transporter object using the default SMTP transport let transporter = nodemailer.createTransport({ host: "smtp.sendpost.io", port: 587, secure: false, // true for 465, false for other ports auth: { user: "" , // generated ethereal user pass: "", // generated ethereal password }, requireTLS: true, debug: true, logger: true, }); // send mail with defined transport object try { let info = await transporter.sendMail({ from: '[email protected]', to: '[email protected]', subject: 'Test Email Subject', html: 'Hello Geeks!!!', }); console.log("Message sent: %s", info.messageId); } catch (e) { console.log(e) } } main().catch(console.error); ``` For PHP ```php
