FAQ
Can I have multiple providers?
Yes — separate records per SMTP account, WhatsApp number, or vendor. Link each on Transaction Configs.
Where do API credentials go?
On the provider edit form. Passwords and tokens are stored securely and never shown again after save — use SMTP Password Set / has-password indicator on view.
What is Phone Number ID?
WhatsApp Cloud API sender identifier from Meta Business Manager — not the display phone number customers see.
Test email says authentication failed (535).
Use app-specific passwords for Gmail/Microsoft; match port and encryption; verify username is full email. See Email FAQ.
Can I suspend a provider temporarily?
Suspend stops new sends using that provider. Update or suspend Transaction Configs that reference it before deletion.
Do providers send in-app notifications?
No. Providers are for outbound WhatsApp/email. In-app inbox uses Notifications subscriptions.
Why are messages failing in Transaction History?
Check credentials, template approval (WhatsApp), recipient format, and Failed row error text in Transaction History.
