Connect Formidable Forms to Brevo

Connect Formidable Forms to Brevo and every form submission becomes a contact in the Brevo list you choose. The free ClickSyncr for Brevo plugin adds a Brevo form action, available in Formidable Lite as well as Pro: connect your API key once, pick a list, map your fields, save. So there is no code, and it takes about two minutes per form.

Before you begin

You need three things: the ClickSyncr for Brevo plugin activated, Formidable Forms active, and a Brevo account with permission to create an API key. You store the key once, and every supported builder on the site then shares it.

Get your Brevo API key

1. Log in to Brevo and go to Settings → SMTP & API → API Keys.
2. Generate a new v3 API key and give it a recognisable name such as WordPress ClickSyncr.
3. Copy it and paste it into any ClickSyncr Brevo panel. One key serves the whole site.

Treat the key like a password. Anyone holding it can read and modify your Brevo lists and contacts.

Formidable Forms setup, step by step

1. Open the form’s actions and add ClickSyncr Brevo. From Formidable → Forms, edit a form and open Settings → Actions & Notifications. Add the ClickSyncr Brevo action.
2. Paste your Brevo API key and connect. Also, you store the key once, and every other form and builder reuses it across every ClickSyncr Brevo surface on the site, so other forms and builders reuse the same connection.
3. Choose the Brevo list. In fact, the dropdown lists every list in your account with its contact count, so you can tell them apart at a glance.
4. Map your form fields. Then Email is the required mapping; every other row targets one of your Brevo contact attributes, such as FIRSTNAME, LASTNAME or SMS, loaded with their types once the key connects.
5. Optional: set a consent field. Also, choose a checkbox, acceptance or radio field to drive opt-in. Ticked adds the contact right away; unticked sends Brevo’s double opt-in confirmation email instead, so the contact only joins the list after confirming.
6. Update the form. In addition, submissions now sync on every entry.

Typed attributes, mapped safely

Brevo identifies contacts by email, so Email is the one required mapping. Every other row maps to your account’s contact attributes, such as FIRSTNAME, LASTNAME, SMS and any custom attributes you have created, and ClickSyncr loads them with their types once the key connects. ClickSyncr converts values to each attribute’s real type: a number field arrives in Brevo as a number, a checkbox as true or false, not as text. Also, ClickSyncr simply skips an unmapped field and never overwrites existing contact data with a blank value. If a visitor types an invalid phone number, ClickSyncr drops only that field and still syncs the contact.

Contact status and double opt-in

Each form chooses how contacts arrive: added right away (the Brevo default), or confirmation email, which uses Brevo’s double opt-in so the contact only joins the list after clicking the confirmation link. The confirmation path needs a double opt-in template in your Brevo account. A consent field overrides it per submission: ticked adds right away, unticked sends the confirmation email. Brevo matches contacts by email, so it updates existing contacts instead of duplicating them.

Verify the sync

First, submit the form on the front end (not the admin preview) with a test address you can recognise, filling every mapped field. Then, in Brevo, open Contacts and confirm the contact exists, sits in the list you selected, and carries the mapped attribute values with their proper types. In short, that one minute catches almost every configuration mistake.

Troubleshooting

Does the action work in Formidable Lite?

Yes. The ClickSyncr Brevo form action registers in the free Formidable Lite as well as Formidable Pro.

Can different Formidable forms use different lists?

Yes. Each form’s action chooses its own list and field map while sharing the site-wide key.

Frequently asked questions

Which Formidable Forms consent values allow a submission to reach Brevo?

The consent check recognises yes, true, on, checked, and the checked value 1. It rejects empty answers and explicit negatives such as no, false, off, and unchecked. Recognised checkbox types can also use another nonempty value unless it is an explicit negative. Choose the actual consent input in Formidable Forms, then test its checked and unchecked answers.

Why is a Brevo contact attribute missing from the Formidable Forms mapping?

The attribute loader includes only Brevo attributes in the normal category. A named attribute from another category is therefore excluded even when the account connection works. Check the attribute’s category in Brevo before changing the Formidable Forms field. Compare the available mapping choices after refreshing, and map only attributes that the integration actually offers.

Why do Brevo sync counts stay unchanged after a Formidable Forms submission?

ClickSyncr excludes skipped results from both success and failure counts. Missing form credentials, a missing destination, an invalid email, or refused consent can therefore leave the counters unchanged. Test a newly created Formidable entry against the ClickSyncr action configured for that form. Then submit a valid test with consent given. A stationary counter alone does not establish whether the contact was sent to Brevo.
