Step-by-step guide to connecting a WhatsApp Business number to Meta's official API
Connecting a number to Jestor's native WhatsApp requires three things — a Jestor account, a WhatsApp number, and a Facebook Business account —, and the whole process is usually ready the same day.
Why does this process seem more complicated than it actually is?
A lot of people get stuck thinking they need advanced technical knowledge, when in practice the steps are guided — most of the wait time comes from Meta's own verification process.
How to connect the WhatsApp number to the official API?
- The first step is getting a WhatsApp number, if you don't already have a dedicated one.
- In Jestor, the connection starts at "new number, connect with Facebook."
- You'll need to choose, or create, a business portfolio and a WhatsApp Business account within Meta.
- Number verification happens via SMS.
- Once connected, it's recommended to register a payment method with Meta.
- The last step is linking that number to a specific table and mapping the fields.
| No payment method registered | Does it work? |
|---|---|
| Receiving and replying manually | Yes |
| Sending automatic templates | No |
To connect the number, step by step:
- Get the number, if needed.
- Start the connection under "new number" inside Jestor.
- Authorize through the Meta screen.
- Confirm via SMS.
- Register a payment method (optional, but recommended).
- Link the number to a table, defining the field mapping.
Why choose Jestor to connect WhatsApp Business without the hassle?
Having this connection process guided right from inside the platform reduces the chance of error in an integration that would otherwise require technical knowledge of WhatsApp's official API.
Frequently asked questions
Does a regular phone number work for this integration?
Yes, although a dedicated virtual number for the official API is the most recommended option.
Do I need a Facebook Business account before starting?
Not necessarily, you can create one during the connection process itself.
If I don't register a payment method with Meta, does WhatsApp stop working?
No, but automatic template sending stays unavailable without a registered payment method.
How long does it take for the number to become active?
Setup is quick, but Meta's verification can take a few hours on new accounts or numbers.
