The WhatsApp Channel for Your Braze Segments.

How the Braze WhatsApp Integration Works in Detail

Chatarmin handles WhatsApp communication, while Braze remains the platform for your wider customer engagement. The integration keeps WhatsApp customer data in Chatarmin aligned with profiles, segments and campaigns in Braze.

What Flows From Chatarmin to Braze

When a contact changes in Chatarmin, the integration can update the matching Braze profile. That covers WhatsApp consent in the attribute of your choice (default: chatarmin_whatsapp), tags in Chatarmin_Tags, the tag count in Chatarmin_Tag_Count, custom properties with the chatarmin_ prefix, the birthday in chatarmin_birthday, plus first name, last name, email address and phone number in the standard fields. Chatarmin also sends two events: "Chatarmin - Flow enrolled" when a contact enters a flow, and "Chatarmin - Updated Profile" when Chatarmin syncs or updates the profile. Contact changes reach Braze shortly after they happen in Chatarmin.

What Chatarmin Uses From Braze

Chatarmin loads the segment list and the attributes from your Braze account. You use the segments in the segment builder and in the Braze Segments if/else condition, and the attributes in the Braze Properties condition and the Update Braze Properties action. If Braze holds a name or email address that is missing in Chatarmin, Chatarmin can use that information. Braze can also start a Chatarmin flow itself: a webhook from Braze, for example from a Canvas, triggers the flow as long as it contains the customer details.

How Contacts and Profiles Are Matched

Chatarmin matches profiles using the contact's phone number, email address or external ID. Keep one Braze profile per Chatarmin contact and merge old or test duplicates in Braze, so every match stays unambiguous.

What You Need for the Connection

In Braze you create a REST API key under Settings, APIs and Identifiers with six permissions: users.track, users.export.ids, users.identify, users.export.segment, segments.list and custom_attributes.get. In Chatarmin you go to Integrations, Braze and enter the key and the REST endpoint of your Braze instance, for example https://rest.fra-02.braze.eu for Braze EU. You then choose whether WhatsApp consent is synced automatically. You usually do not need a developer for this.

Reaching Lapsed Customers Through a Braze Segment

Your CRM team maintains a segment in Braze for customers who have not bought in a while, for example "Lapsed Users". In Chatarmin you turn it into an audience: contacts in that Braze segment who have opted in to WhatsApp. You send a WhatsApp campaign to that audience or enrol it in a flow.

Inside the flow you keep branching on Braze data. An if/else condition checks a segment or an attribute, and Update Braze Properties records what the contact told you on WhatsApp. The segment logic stays in Braze, so you do not build a second one in Chatarmin.

What Braze Knows After a WhatsApp Journey

When a contact enters a flow, the event "Chatarmin - Flow enrolled" lands in their Braze profile. When Chatarmin updates the profile, "Chatarmin - Updated Profile" follows. Your team uses both events in Braze for reporting, analytics, segments and campaigns.

The profile attributes tell the story too. Consent sits in the attribute you chose during setup, and the tags from Chatarmin sit in Chatarmin_Tags. That lets you build segments in Braze such as "has WhatsApp consent" or "carries the VIP tag from Chatarmin".

Who the Braze WhatsApp Integration Is For

The integration fits brands that run their customer engagement in Braze and want to add WhatsApp as a channel. A lot of work usually goes into Braze: profiles, attributes, segments and a team maintaining them daily. Chatarmin uses those segments and writes back, rather than building a second data set.

When Your CRM Team Segments in Braze

Your segments are created in Braze and stay there. In Chatarmin you select them as a filter and branch on them inside a flow. Flow enrolments and profile changes from Chatarmin come back to the profile as events and attributes, so your team can build the next campaign in Braze on top of it.

When Compliance Has a Seat at the Table

Chatarmin is an official Meta Business Partner, certified to ISO 27001, GDPR-compliant and hosted on servers in Europe. With consent sync turned on, WhatsApp consent sits as an attribute on the Braze profile. If you work with Braze EU, you enter the REST endpoint of your EU instance during setup.

When You Want to Start Without a Developer Project

For the connection you need a REST API key with the required permissions and the REST endpoint. Your Braze admin can create the key if needed, and you usually do not need a developer.

What Does the Braze WhatsApp Integration Cost?

Meta charges per message. A marketing message costs €0.1131 in Germany, so around 11 cents. In Austria and Switzerland it is €0.0490, so around 5 cents. A utility message such as a shipping notification costs €0.0456 in Germany. Since 1 October 2026 service messages are charged as well, also €0.0456 in Germany. A marketing campaign to 10,000 contacts in Germany therefore costs you around €1,131 in Meta fees. These figures follow the Meta rate card in force since 1 July 2026.
