Create OAuth bearer token

<Note icon="fa-regular fa-circle-info"> **Note – Access tokens for embedded experiences require specific API key**

Before calling this endpoint to obtain an access token for embedded experiences (second scenario above), you must obtain a dedicated API key. To do so, contact Mangopay <a href="https://hub.mangopay.com/" target="_blank">via the Dashboard</a>.

Once you have the dedicated API key, encode it in the usual way by using Base64 to encode your Client ID and dedicated API key separated by a colon (ClientId:ApiKey). For more information, read the OAuth 2.0 authentication guide. </Note>

Generate an OAuth bearer token to authenticate your API calls

This endpoint allows your to generate a bearer token to authenticate subsequent API calls. There are two scenarios, one of which is handled for you if using the server-side SDKs.

Firstly, this endpoint can be used to generates a bearer token to authenticate all calls to the Mangopay API as part of OAuth 2.0 authentication. The server-side SDKs handle this first authentication scenario for you by generating and refreshing the token before expiry.

Secondly, you can use a specific API key with this endpoint to generate a bearer token that subsequently allows you to generate another access token to initialize a Mangopay embedded experience. Once you have the bearer token, you can call one of two endpoints to obtain an access token:

• POST Create an access token for the Recipients embedded experience to obtain a token to run the Recipients frontend experience using Mangopay Elements
• POST Create an access token for Checkout SDK to obtain a token to initialize Checkout SDK with PayPal One-Click
