Business portfolio pacing | Developer Documentation

Why a WhatsApp campaign may slow across several numbers

Meta can release a large template campaign in batches while it checks early customer feedback. When the check applies to a business portfolio, messages sent from several numbers in that portfolio can be affected. Some recipients may receive a message while others remain pending. A request accepted for processing is not proof of delivery.

Portfolio pacing is different from template pacing, which concerns a particular template. It is also different from a phone number's sending throughput. A held status alone does not identify which mechanism applies to your campaign.

Check the scope of the delay

1. In the connected tools, compare final message outcomes for several templates and business numbers. Note which recipients have a delivered, failed, or still unknown outcome. If the tool does not show final statuses, ask ChatArchitect support to check them.
2. If your integration exposes Meta's technical status, record held_for_quality_assessment for affected messages. This indicates a hold for review, but does not by itself prove that the whole portfolio is paced.
3. If you administer the Meta business portfolio, check Meta Business Suite or WhatsApp Manager for account notices. Record any restriction shown there and share its wording with ChatArchitect support.

What to do before another send

• Avoid launching another large batch from a different number while outcomes are still unknown. Some held messages may be released later, and sending them again can create duplicates.
• Review the recipient list, consent, sending frequency, and template quality. A problem with one template may need a different response from a portfolio review.
• Give ChatArchitect support the connected numbers, template names and languages, campaign time, affected recipient examples or message IDs, and any error or account notice. Ask whether Meta is holding messages for portfolio or template review and which recipients still need a send.

Meta may release held messages or mark them failed after review. There is no guaranteed release time. Check final outcomes before resuming a time-sensitive campaign. If Meta has paused a template, follow the pause guide before using it again.
