To send a form on WhatsApp, HueChat needs an approved template with a website button. HueChat puts a private invitation in that button for each recipient, so every answer is linked to the right customer. This article shows you how to create the template in WhatsApp Manager.

Template name, language and category
visit_feedback_ar.{{1}}, not named variables.
Header, body and footer
Write the body as a follow-up to something the customer did, such as a recent visit. Meta approves that kind of message as Utility. Promotional wording, or a general request such as "rate us", is often classed as Marketing. Do not put a link in the body. The link goes in the button.

The finished button link must be exactly https://app.huechat.ai/to/<form code>?invite={{1}}. Nothing can come after {{1}} and the link cannot contain other variables. Otherwise HueChat cannot attach your form to the template.
You can also add a second button: a Custom quick reply, such as تواصلوا معي, whose text arrives in your inbox when a customer taps it, or a Call phone number button so customers can call your clinic or store.
Check the Template preview, then choose Submit for review. Meta usually responds within minutes to a day. If Meta moves the template to the Marketing category, HueChat cannot use it for forms.
If Submit for review stays grey, click outside the last field you edited. If it is still grey after you changed the type of a button, reload the page and create the template again.
When the template is approved, it appears in HueChat. If you cannot find it, sync templates from the WhatsApp inbox settings. Then choose it where you send forms:
HueChat fills {{1}} with a new private invitation for each customer. If you send the template another way, for example directly from WhatsApp Manager, the button opens a link that does not work.
