Generate Authorization Token

Before you can create a payment link or check its status, you need to authenticate your system by generating an Authorization token. This token acts as a secure key that confirms your system is allowed to interact with the PhonePe Payment Gateway.

Use this token in the Authorization header for all subsequent API calls.

Response Parameters

Parameter Name	Data Type	Description
`access_token`	String	The token generated by PhonePe. This token is valid for a specific time, which can be determined using the expires_at field. Once expired, the token must be refreshed using the same API.
`issued_at`	DateTime	The timestamp in epoch (in seconds) when the token was generated
`expires_at`	DateTime	Token expiry timestamp in epoch
`token_type`	String	The type of token, which will be O-Bearer.

ℹ️ Access Token Guidelines!

You should depend on the following key response parameters:
- access_token: This is the token that must be included in API calls with PhonePe for authentication.
- expires_at: This indicates the token’s validity (in seconds). You must ensure that the token is refreshed before it expires. If it expires, you will have to send the request again.
The auth_token is required for all subsequent API calls. Use the above access token to initiate the payment process.
