Webhook Authentication

You can authenticate inbound webhooks using an HMAC-SHA256 signature. TexterID computes the signature over the payload, signed by the client API key (canonical JSON including null fields). For example code, please visit our public GitHub repository with code samples.

If you require a set of whitelisted IPs for your network gateway to allow inbound requests, we can provide a list. Please get in touch with your account manager or email [email protected].
