What authentication does the MegaAPI use?

MegaAPI uses HTTP Bearer authentication. Pass an Authorization: Bearer <token> header on every request, where the token is the API key associated with your MegaAPI account. Through Jentic the bearer token is stored encrypted and injected at call time, so it never enters the agent's prompt context.

Can I send media files larger than the WhatsApp limit?

MegaAPI exposes two media-send paths - POST /rest/sendMessage/{instance_key}/mediaUrl for hosted files and POST /rest/sendMessage/{instance_key}/mediaBase64 for in-line base64 - but the underlying WhatsApp transport still enforces the standard 16 MB media size cap. For larger files, host them externally and send the link with POST /rest/sendMessage/{instance_key}/sendLinkPreview instead.

What are the rate limits for MegaAPI?

Rate limits are not declared in the OpenAPI spec and are governed by your MegaAPI plan and by WhatsApp's own anti-spam thresholds. As an unofficial gateway the practical guidance is to keep outbound throughput conservative - bursts of broadcast traffic are the most common cause of instance bans.

How do I send a WhatsApp text message through Jentic?

Run pip install jentic, then search Jentic for 'send a WhatsApp text message', load the schema for POST /rest/sendMessage/{instance_key}/text, and execute it with the instance_key, recipient phone number, and message body. Jentic injects the bearer token from your stored credentials. Run it through Jentic One, the self-hosted execution layer.

How do I receive incoming WhatsApp messages?

Configure a webhook on your instance with POST /rest/webhook/{instance_key}/configWebhook, pointing at an endpoint you control. MegaAPI then POSTs every inbound message and event to that URL. You can read or update the current webhook config at any time via GET /rest/webhook/{instance_key}.

Can I limit what my agent is allowed to do with the MegaAPI?

Yes. Because you run Jentic One yourself, your own rules decide which MegaAPI operations and credentials the agent may use. MegaAPI carries the instance_key in every URL path, so a rule can pin the agent to a single WhatsApp instance and let it only send messages via POST /rest/sendMessage/{instance_key}/text and read that instance's groups via GET /rest/group/list/{instance_key}. You choose the operations it may call, so instance configuration such as POST /rest/webhook/{instance_key}/configWebhook stays off limits unless you explicitly add it.
