A BSP (Business Solution Provider) is a Meta-authorized partner — Twilio, Interakt, Wati, AiSensy, Gallabox, and others — that resells access to the WhatsApp Business API. See What Is a WABA (WhatsApp Business Account)? for the full definition. The question that actually matters if a business already has one: can they switch to ChatSyncs without starting over?

​
The short answer: yes

  • The phone number and WABA belong to the business’s Meta Business Portfolio — not to the BSP.
  • A BSP is just the middleman that was given permission to use it.
  • Moving to ChatSyncs means swapping who has that permission — not creating a new WABA from scratch.

​
What moves over automatically

Because these live in Meta, not in the old BSP:
  • The phone number itself
  • The WABA and its approved message templates
  • The number’s quality rating and messaging tier
  • Meta’s own conversation history record

​
What does NOT move over automatically

Anything the old BSP stored on its own side has to be rebuilt in ChatSyncs:
  • Its bot flows, automations, and keyword replies
  • Its own contact tags, segments, or custom fields
  • Its own local chat log / mirror (separate from Meta’s own record)
  • Any custom integrations built specifically on that BSP’s platform

​
How to actually switch

1

Remove the old BSP's access in Meta

A WABA can only have one partner with Full access at a time. Follow How to Disconnect Another Partner From Your WhatsApp Number — including the extra phone-side step if the old setup used Coexistence.
2

Connect the number to ChatSyncs

Use How to Connect Your Number to ChatSyncs if you don’t have your own Meta app credentials handy, or How to Connect Your WhatsApp Account Manually (Alternative Method) if you do.
3

Re-sync templates and rebuild automations

Pull existing approved templates into ChatSyncs — see Sync Templates from WhatsApp Manager — then rebuild any bot flows or automations that lived only in the old BSP.

​
Frequently asked

No — the number stays yours in Meta regardless of which BSP or platform currently has API access to it.
Yes, templates live on the WABA inside Meta, not inside the old BSP. See Sync Templates from WhatsApp Manager to pull them into ChatSyncs.
No — quality rating is tracked by Meta against the phone number itself, not against whichever platform is currently connected to it.
Not required for the technical switch — removing their partner access in Meta is enough. Cancel any separate subscription you had directly with them on your own.
No — only one partner can hold Full access to a given WABA at a time.

Gotchas & common mistakes

  • Coexistence connections need an extra step. If the old BSP connection used Coexistence (the WhatsApp Business App active on a phone), disconnecting in Meta alone isn’t enough — the app itself also remembers the old partner. See the second half of How to Disconnect Another Partner.
  • Don’t wait to remove old access before connecting to ChatSyncs — the new connection will fail with an “already linked” error until the old partner’s access is removed first.
