Introduction

Mangopay provides a regularly updated Postman collection for you to test the Mangopay API in the Sandbox environment.
Mangopay API Postman collection
Prerequisites
Click Run with Postman to fork the collection into your workspace:
Run with Postman
Best practice – Watch the collection for updatesWatch the collection by clicking the eye icon on the parent folder to receive an email when new additions and changes are merged.You can then pull the changes to bring your fork up to date.

​
Set up your environment

Once the collection is forked, make sure you’ve selected the relevant environment and set up the key variables if they are not already defined: We also recommend you set variables used for some specific calls:
  • CURRENCY – Enter the default currency for your tests. Keep in mind that some payment methods don’t support all currencies, so you might need to update them manually at times.
  • CULTURE – Enter the default culture value. The Culture parameter is mostly used in web payment methods, but keep in mind that payment methods don’t necessarily support the same values. We recommend you use EN for a better experience.
Note - Other variables populated automaticallyWhere relevant, calls in the collection contain post-request scripts (in the Scripts tab of the request) that populate other variables based on the response from the API.For example, the Create a Natural User call populates a USER_NATURAL_PAYER variable with the returned Id; Create a Wallet populates a WALLET_ID, and so on. Likewise, during the card registration process, the tests populate the tokenization data automatically, meaning you should be able to submit the calls one after another without having to copy and paste values manually.

​
Authenticate Postman calls

The Mangopay API uses OAuth 2.0 to authenticate calls, which is supported by Postman. In Postman, authentication for the collection is managed in the Authorization tab of the parent folder. Child folders and individual calls inherit this authentication. In the Authorization tab, ensure:
  • The Access Token URL field contains the ENV_URL variable followed by /v2.01/oauth/token to call the OAuth token endpoint.
  • The Client ID field contains the CLIENT_ID variable.
  • The Client Secret field contains the API_KEY variable.
  • All the variables are showing blue, indicating that they are defined, and not red.

​
How to generate the first token

Note – Postman auto-refreshes tokensPostman can automatically refresh the OAuth token, but the first token needs to be generated manually.You also need to generate a new token manually if you change from one collection to another, or from one set of API credentials (Client ID and API key) to another.
  1. On the Authorization tab of the collection, scroll down to the bottom and click on Get new access token.
  2. Postman calls the OAuth token endpoint to get a token. Once done, click Proceed (Postman proceeds automatically after 5 seconds).
  3. In the Manage access tokens dialog, you can see the details of the generated token. On the left, you can see all other tokens with the option to delete expired tokens. Click Use token to add the token to the Authorization tab and use it to authenticate calls.

​
Collection structure

The Mangopay API Postman collection is built with variables and scripts to so that you can test a flow of actions more easily. In the Workflows and tutorials folder, you’ll find folders of groups of collections ordered for specific use cases. In the All API endpoints folder, you’ll find the API endpoints grouped by topic or object (approximately following the docs API reference navigation). You’ll also find comments with specific guidance in the body of relevant requests.

Stay up to date

The Mangopay API Postman collection is regularly updated by Mangopay teams. Watch the collection to be notified of updates via email, and then pull the changes to bring your fork up to date.
