Call Authentication

Learn how to authenticate your API requests to call the EngageLab SMS service.

The EngageLab SMS API uses HTTP Basic Authentication. All API requests must include an Authorization header.

Authorization Header Description

The format of the Authorization header is as follows:

Authorization: Basic ${base64_auth_string}

              
              Authorization: Basic ${base64_auth_string}

Generate Authentication String

${base64_auth_string} is obtained by joining your dev_key and dev_secret with a colon (:) and encoding it in Base64.

Algorithm:

base64(dev_key:dev_secret)

              
              base64(dev_key:dev_secret)

You can find your dev_key and dev_secret in the APIKey section of the EngageLab SMS Console. Please keep your dev_secret safe and never leak it in public code.
