Your application should map numeric codes to actions \u2014 never parse the message string.<\/span><\/p>\n<h3><b> Implement exponential backoff for rate limits<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Whenever you hit code 130429, 4, or 131056 \u2014 back off. Start with 1 second, double on each retry, and cap at 60 seconds. Hammering the API after a rate limit hit only makes things worse.<\/span><\/p>\n<h3><b> Always validate phone numbers in E.164 format<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Every number you send to should be in full international format \u2014 like <\/span><span style=\"font-weight: 400;\">+919876543210<\/span><span style=\"font-weight: 400;\">. No spaces, no leading zeros. A badly formatted number is often the cause of silent delivery failures (code 131026).<\/span><\/p>\n<h3><b> Confirm template approval before every send<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Before a bulk campaign, pull your template list via API and confirm the status is <\/span><span style=\"font-weight: 400;\">APPROVED<\/span><span style=\"font-weight: 400;\">. Templates can get paused by Meta at any time based on quality signals. Sending to a paused template wastes quota and may further hurt your quality rating.<\/span><\/p>\n<h3><b> Monitor webhooks continuously, not just API responses<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Async errors arrive via webhook. If your system only checks API response codes, you&#8217;re blind to a whole category of failures.
