Client ID and Client Secret are unique credentials for each customer application that are required to access any subscribed APIs. As part of the onboarding process on the API Portal, Partners need to create an application. On approval of the application, the Client ID and Client Secret will get generated automatically on the API Portal. The Client ID needs to be utilized as the value of the  API key to be sent in the API request header.

In cases where the API indicates that OAuth is needed, the Client ID is additionally used as ‘Username’ while Client Secret is used as the value of 'Password' in the Authorization Headers for the OAuth API call (More details on OAuth API is available in the Technical User Manual).

Client ID and Client Secret can be accessed on the API Portal, within the Partner’s application, in the AUTH tab. These values are unique for each application created by you on HDFC Bank’s API Portal.

Client ID and Client Secret values are generated automatically and partners cannot change them.
