Integration Details

Integration of New Whatsapp Provider

Whatsapp provider is a third-party service that works in the middle of a user's WhatsApp client and XState-Chatbot server. All messages coming/going to/from user pass through WhatsApp provider. Chatbot calls WhatsApp provider to send messages to the user. When a user responds with any WhatsApp message the WhatsApp provider calls Chatbot service’s configured endpoint with details ex:- user sent message, sender’s number etc.

If any new WhatsApp provider is to be used with a chatbot, code must be written to convert the provider’s incoming messages to the format that the chatbot understands and also final output from the chatbot should be converted to WhatsApp provider’s API request format.

Currently, the XState-Chatbot service is using ValueFirst as the WhatsApp Provider. This will require provider-specific environment variable to be configured. If the provider changes then, all these environment variable will also change. Few of those environment variables are stored as secrets, so these values need to be configured in env-secrets.yaml.

As this is a revamped version of the chatbot service, all of the secrets should already be present. There is no need to create new secrets.
