Any application sending payment links with Chat 2 Pay needs an API key authorizing the transaction request. The activation key is generated and presented to you once the Chat 2 Pay configuration is complete. This is the key you'll use to activate your linked applications. All applications use the same activation key.

You can have multiple activation keys for the same Chat 2 Pay account. However, you can only use one activation key at a time to authorize a transaction.

If your activation key has been compromised, you can create a new activation key and delete the compromised key.
