# Introduction JTL-FFN is a standardized interface for fulfillment service providers and their customers. Fulfiller can offer their services to merchants and merchants can respectively choose from a wide range of service providers according to their needs. ## The ecosystem The FFN network consists of this REST API, an online portal and third party integrations (JTL-Wawi being one of them). The REST API orchestrates the interactions between the participants and the portal website provides services by JTL (such as managing and certifying warehouses of a fulfiller and merchants searching for their service providers). ## About this API The base url of this api is [https://ffn2.api.jtl-software.com/api](https://ffn2.api.jtl-software.com/api). This API (and this documentation) consists of three parts: * Fulfiller API - operations used when acting as a fulfiller in the network. Only users with the role `Fulfiller` can access these endpoints. * Merchant API - operations used when acting as a merchant in the network. Only users with the role `Merchant` can access these endpoints. * Shared API - operations available to all users. Please use the navigation menu at the top to switch between the documentation for the different APIs. # OAuth The FFN-API uses [OAuth2](https://tools.ietf.org/html/rfc6749) with the [Authorization Code Grant](https://tools.ietf.org/html/rfc6749#section-4.1) for its endpoints. Users must have an active [JTL customer center](https://kundencenter.jtl-software.de) account to authorize against the OAuth2 server. Applications and services using the API must acquire client credentials from JTL. ## Application credentials When making calls against the API, you need to do it in the context of an application. You will get the credentials for your application from JTL. Application credentials consist of the following: * `client_id` - uniquely identifies your application * `client_secret` - secret used to authenticate your application * `callback_uri` - the uri the OAuth2 server redirect to on authorization requests ## Requesting authorization When you want to authorize a user you redirect him to `https://oauth2.api.jtl-software.com/authorize` with the following query string parameters: * `response_type` - Must be set to "code" for the [Authorization Code Grant](https://tools.ietf.org/html/rfc6749#section-4.1). * `redirect_uri` - After the user accepts your authorization request this is the url that will be redirected to. It must match the `callback_uri` in your client credentials. * `client_id` - Your applications identifier from your application credentials. * `scope` - The scopes you wish to authorize (space delimited). * `state` - An opaque value that will be included when redirecting back after the user accepts the authorisation. This is not required, but is important for [security considerations](http://www.thread-safe.com/2014/05/the-correct-use-of-state-parameter-in.html). After successful authorization by the user, the OAuth2 server will redirect back to your applications callback with the following query string parameters: * `code` - The authorization code. * `state` - The state parameter that was sent in the request. ## Verifying authorization The authorization code you acquired in the last step will now be exchanged for an access token. In order to do this you need to POST a request to `https://oauth2.api.jtl-software.com/token`. >POST > >Authorization: Basic `application_basic_auth`\ >Content-Type: application/x-www-form-urlencoded > >grant_type=authorization_code&code=`code`&redirect_uri=`redirect_uri` In the Authorization header [Basic HTTP authentication](https://tools.ietf.org/html/rfc7617) is used. Your application credentials `client_id` will be used as the username and your `client_secret` as the password. The header should have the value "Basic" plus the Base64 encoded string comprising of `client_id:client_secret`. The body of the request consist of the form encoded parameters: * `grant_type` - Must be set to "authorization_code". * `code` - The authorization code received from the previous step. * `redirect_uri` - Must match the `callback_uri` in your client credentials. A successful verification request will return a JSON response with the properties: * `token_type` - is always "Bearer" * `expires_in` - the time in seconds until the access token will expire * `access_token` - the access token used for API requests * `refresh_token` - token used to get a new access_token without needing to ask the user again Now the APIs endpoints that need authorization can be called by setting the header >Authorization: Bearer `access_token` ## Refreshing authorization To get a new `access_token` (for example when the old one expired) one can POST a request to `https://oauth2.api.jtl-software.com/token`. >POST > >Authorization: Basic `application_basic_auth`\ >Content-Type: application/x-www-form-urlencoded > >grant_type=refresh_token&refresh_token=`refresh_token` The Basic HTTP Authorization works exactly as in the verification step. The body of the request consist of the form encoded parameters: * `grant_type` - Must be set to "refresh_token". * `refresh_token` - The `refresh_token` you acquired during verification. The response will be the same as in the verification step. ## Scopes Scopes allow fine grained control over what actions are allowed for a given application. During login users must approve the requested scopes, so it is often feasible to limit asking for permissions your application really needs. Global scopes for common permission scenarios are the following: * `ffn.fulfiller.read` - full read access for the fulfiller API * `ffn.fulfiller.write` - full write access for the fulfiller API * `ffn.merchant.read` - full read access for the merchant API * `ffn.merchant.write` - full write access for the merchant API More fine grained scopes can be acquired from each respective endpoints documentation. ## Example ### Prerequsites * JTL Customer center account (https://kundencenter.jtl-software.de/) * cUrl (https://curl.se/) * FFN portal account (just login here: https://fulfillment.jtl-software.com) * FFN portal sandbox account (if you want to test on sandbox: https://fulfillment-sandbox.jtl-software.com) * Oauth Client for authorization and define scopes Values in this example (access_token, refresh_token, code...) are expired and cannot be used verbatim. ### Step 1 - Create an OAuth client Navigate to https://kundencenter.jtl-software.de/oauth and create a new OAuth client. (You can´t navigate to Oauth in customer account, you should use this link, or you can change logged in index to oauth) !Templates define what scopes are possible for this client. scopes with access rights: * ffn.merchant.read - full read access for the fulfiller API * ffn.merchant.write - full write access for the fulfiller API * ffn.fulfiller.read - full read access for the merchant API * ffn.fulfiller.write - full write access for the merchant API More fine grained scopes can be acquired from each respective endpoints documentation.  Overview: clients, scopes, client-secret and client-id  In our example: * client_id: 97170e65-d390-4633-ba46-d6ghef8222de * client_secret: f364ldUw3wGJFGn3JXE2NpGdCvUSMlmK72gsYg1z * redirect_uri: http://localhost:53972/ffn/sso The values for this client should not be used in production and are for testing only. ### Step 2 - User login In this step you will redirect the user to the JTL OAuth website using his default browser. Here the user will provide his username/password and accept the requested scopes. Finally the JTL Oauth website will redirect to the provided redirect_uri and provide the code. Template: authorize specified scopes and get code answer to request the access token ``` https://oauth2.api.jtl-software.com/authorize?response_type=code&redirect_uri=[redirect_uri]&client_id=[client_id]&scope=[scopes] ``` Note: the scopes should be seperated by spaces or %20 Filled with our example values: ``` https://oauth2.api.jtl-software.com/authorize?response_type=code&redirect_uri=http://localhost:53972/ffn/sso/oauth&client_id=97170e65-d390-4633-ba46-d6ghef8222de&scope=ffn.merchant.read%20ffn.merchant.write ``` * enter password  * authorize scopes  * code answer from server  Example of the answer from the OAuth server to our redirect_uri: ``` http://localhost:53972/ffn/sso?code=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 ``` Extract the code and note it for next steps. ### Step 3 - Get an access_token from the code Template: get access token + refresh token ``` curl --location --request POST "https://oauth2.api.jtl-software.com/token" --header "Content-Type: application/x-www-form-urlencoded" -u "[client_id]:[client_secret]" --data-urlencode "grant_type=authorization_code" --data-urlencode "redirect_uri=[redirect_uri]" --data-urlencode "code=[code]" ``` Filled with our example values: ``` curl --location --request POST "https://oauth2.api.jtl-software.com/token" --header "Content-Type: application/x-www-form-urlencoded" -u "97170e64-d390-4696-ba46-d6fcef8207de:f364ldUw3wIJFGn3JXE2NpGdAvUSMlmK72gsYg1z" --data-urlencode "grant_type=authorization_code" --data-urlencode "redirect_uri=http://localhost:49420/oauth" --data-urlencode "code=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" ``` The result will be a JSON answer with the users access_token and refresh_token as well as the expiry in seconds. ``` { "token_type":"Bearer", "expires_in":1800, "access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9. eyJhdWQiOiI5NzE3MGU2NC1kMzkwLTQ2OTYtYmE0Ni1kNmZjZWY4MjA3ZGUiLCJqdGkiOiJlOWVhN2Q0MWI1NDIzNTcyYWU0MDEzYjEzMDZiMGRkNWM3YmQ2ZTNjMDNhYTZmNjQ2M2NlMjUzNTc0ZmUyMWE3NGQyNTIyMTJhODQwMmI1ZCIsImlhdCI6MTY2MTI1MzE0OCwibmJmIjoxNjYxMjUzMTQ4LCJleHAiOjE2NjEyNTQ5NDgsInN1YiI6IjQ2MjA5Iiwic2NvcGVzIjpbImZmbi5tZXJjaGFudC5yZWFkIiwiZmZuLm1lcmNoYW50LndyaXRlIl19.eEwY021wR3BWVp-wbAVQrjfqwFbYqLlOV_ca-cb7-O3Kdpi8mkFQBxfI8rzSiV_1WpAINf4ydV9FR9Ty992SMiAqGJ3T9zDHd68oUDePeq7Xfafp-87UboI2mCfGd7518CoKVLqg5ohb4YCqgC7Dz588FofggCQyDZQSM-8raOgcM-pJ1TT7oRuYuDHsOzCOTPcX2YiGYKCc3M6kxlBy_NjrJoLa4qysLRmPkznWwj0caC7a0VJO5KubvECcMb9D7Byr3UNjI7GiGMAufa770V5qCjrWs4gOsRV-Bn7oQydvsL21qqjBKHcssQrlLZWmrcfKqgBKwfRXIx3Mu5HBCmtHjHMnuvPVEZAj6fEfIwjYSeTAHTHApEwbE7J1MPd8MU0K6X2YEUF315fXN5F3rO3ZL5FdTwcM1E-1-PKubLuMAaE6Lw-QsDtBoI4ESylomCmCCfgLV4Vj-in_oCJUmKXAX0tDSa9y9vb6oAExung_BTJCBemffCtkJ55Px7bvi9JXmwvI0pIFo3QzTUtRbFDizCMrPZvsatFx64mXX3IDoVqXr3uzvdetBIJEj2ngVdGRrKGt4Yboae5oFV2d5jdSZBL28pwGjey__ZB4zLR1DodQ0sOqDWJ3WsEjMYXU8_-IGrS8Kkw8Q0R0UqqyVLfcLr-cfH5tYqf2QLqAScY","refresh_token":"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" } ``` ### Step 4 - Test the access_token Using your newly aquired access_token you can test if its working (reminder: the access_token has a limited lifetime and might be expired, in which case we would need to refresh it (see Step 5)). Template: Test communication with access token on sandbox or production (our client is for both systems) ``` curl --location --request GET "https://ffn-sbx.api.jtl-software.com/api/v1/users/current" --header "Authorization: Bearer [access_token]" ``` If you cannot retrieve the user data using this endpoint make sure you have logged into our respective portal website (sandbox, production) at least once as this triggers user creation in the system. ### Step 5 - Refresh access_token when it expires Template: Get a new access token + refresh token with the refresh token ``` curl --location --request POST "https://oauth2.api.jtl-software.com/token" --header "Content-Type: application/x-www-form-urlencoded" -u "[client_id]:[client_secret]" --data-urlencode "grant_type=refresh_token" --data-urlencode "refresh_token=[refresh_token]" ``` Filled with our example values: ``` curl --location --request POST "https://oauth2.api.jtl-software.com/token" --header "Content-Type: application/x-www-form-urlencoded" -u "97170e64-d390-4696-ba46-d6fcef8207de:f364ldUw3wIJFGn3JXE2NpGdAvUSMlmK72gsYg1z" --data-urlencode "grant_type=refresh_token" --data-urlencode "refresh_token=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" ``` The result will be the same format as in step 3. Refresh_tokens are only valid for a single refresh and you will get a new refresh_token every single time that you must persist. ### My token is not working! #### 404 NotFound You need to log into the respective portal website (sandbox-https://fulfillment-sandbox.jtl-software.com, production-https://fulfillment.jtl-software.com) at least once to trigger user creation. #### 403 Forbidden You might be missing scopes in your token and don't have sufficient rights. #### 401 Forbidden Incorrect Oauth method. For example, we do not support the Oauth method authorisation "client_credentials grant". The authorisation method "code grant" with user must be used.
