# Handling WhatsApp Business API Integration Issues

1. Why are WhatsApp messages delayed or not getting delivered?

Possible Causes & Solutions:

* Check API Rate Limits: Verify if the WhatsApp Business API is throttling messages due to exceeding rate limits.
* Monitor Message Queue: Check if messages are queued due to high outbound traffic.
* Review Webhook Logs: Ensure that webhook responses from WhatsApp are being received in the CRM.
* Check Business Verification Status: Ensure that your WhatsApp Business Account is fully verified.
* Network & Firewall Issues: Confirm that there are no network restrictions blocking the API requests.

2. Why are my WhatsApp message templates getting rejected?

Possible Causes & Solutions:

* Non-Compliant Content: Ensure that the template follows WhatsApp’s guidelines (no promotional or misleading content).
* Formatting Errors: Use correct placeholders (e.g., {{1}}, {{2}}) and avoid excessive capitalization or special characters.
* Check Template Category: Ensure the template is categorized correctly (e.g., Utility, marketing).
* Verify Business Compliance: Ensure that your business adheres to WhatsApp's policies.
* Appeal Rejected Templates: If a template is wrongly rejected, appeal through the WhatsApp Business Manager.

3. How do I verify if my WhatsApp API integration is working correctly?

Steps to Verify:

* Send a Test Message: Use the API to send a test message and check delivery status.
* Check Webhook Events: Monitor incoming webhook events for message updates.
* Review API Response Codes: Ensure a 200 OK response is received for API requests.
* Debug Logs: Enable debug mode to capture integration issues.

5. How can I resolve template message delivery failures?

Possible Causes & Solutions:

* User Opt-In Issues: Ensure the recipient has opted in to receive WhatsApp messages.
* Incorrect Phone Number Format: Use the correct international format (e.g., +91 for India).
* Message Personalization Issues: Ensure correct placeholder values are being passed in API requests.
* Account Suspension: Check if the WhatsApp Business Account has any restrictions.
