Button
Prerequisites
Before creating a Button credential, you need to obtain authentication credentials from your Button account. Button uses Basic Authentication with a username and password combination to authenticate API requests.
To use Button with Nexla, you need:
- Access to your Button account
- A Button account with appropriate permissions to access the audiences, transactions, and orders you want to work with
- Your Button username and password for Basic Authentication
For detailed information about Button authentication and credential setup, refer to the Button API documentation.

Credential Name & Description

Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.
Resource descriptions are recommended but are not required. They should be used provide information about the resource purpose, data freshness, etc. that can help the owner and other users efficiently understand and utilize the resource.
Basic Authentication Configuration
