Connect Stripe and WhatsApp Cloud API

Stripe records the payment, WhatsApp is where many customers actually read messages. FlowMattic connects the two from your WordPress site: a new subscription, a paid invoice or a cancelled plan in Stripe sends the customer a WhatsApp message through the Cloud API, using the approved templates of your business number.

Stripe and WhatsApp Cloud API workflows you can build

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.

Ready-made template

Send subscription details on WhatsApp when a plan starts

The customer gets the plan name, price and renewal date on WhatsApp right after they subscribe, which answers the first support question before it is asked.

New SubscriptionSend Text Message

View the template

Confirm each successful charge with a template message

Shops and service businesses whose customers prefer WhatsApp send a payment confirmation with the amount and reference, using an approved template so it can open the conversation.

New ChargeNumber FormatterSend Template Message

Send the paid invoice link after payment succeeds

When an invoice is paid, the customer receives the invoice number and its link on WhatsApp, so accountants and clients find it in the chat instead of searching email.

Invoice Payment SucceededSend Template Message

Offer a win-back coupon when a subscription ends

Create a one-time Stripe coupon the moment a plan is cancelled and send its code on WhatsApp, a channel the customer is more likely to open than a farewell email.

Subscription DeletedCreate CouponSend Template Message

Welcome new customers a day after sign-up

A Delay holds the welcome for a day, then a template message shares your onboarding link once the customer has had time to look around.

New CustomerDelaySend Template Message

Alert the owner on WhatsApp about large charges

A Filter lets through charges above the amount you set and messages your own number, so a founder hears about a big order without opening the Stripe dashboard.

New ChargeFilterSend Template Message

Look up the customer's phone before messaging

Invoice events do not always carry a phone number. Find Customer by ID fetches the customer record, and the message goes to the number saved there.

New InvoiceFind Customer by IDSend Template Message

Set up: subscription details on WhatsApp

At the end, each new Stripe subscription sends the customer a WhatsApp message with their plan details.

Connect Stripe

If your checkout stores numbers with spaces or a leading zero, add a Text Formatter step to turn them into the international format WhatsApp expects.
Write the message
Add Send Text Message or Send Template Message, map the phone number and plan details, test the step on your own number and switch the workflow on.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

As the action descriptions say, Send Text Message and the image, video and document actions go to a session the customer created or replied to. To message someone first, use Send Template Message with a template approved for your number.
Stripe holds a phone number only when your checkout or customer form collects one. Add a Filter that stops the workflow when the phone field is empty.
Stripe sends amounts in the smallest currency unit, such as cents. Divide and format them with Number Formatter before they go into the message.
Only message customers who agreed to hear from you on WhatsApp. Ask for that consent at checkout and keep it with the customer record.

Why run this pair with FlowMattic

Stripe and WhatsApp Cloud API connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Payment news where customers read

Confirmations and invoice links arrive in the chat app customers check all day, not in a promotions folder.

Stripe actions in the same flow

Create a coupon or look up a customer in Stripe before the message is sent, so each message carries the right details.

One price for every message run

FlowMattic runs on your own WordPress site with unlimited runs. You pay WhatsApp for conversations, not FlowMattic for each payment.

Common questions

Can Stripe send WhatsApp messages to customers after they pay?

Yes. Use the Stripe New Charge or Invoice Payment Succeeded trigger in FlowMattic, then a WhatsApp Cloud API Send Template Message step mapped to the customer's phone number and payment details.

Why does my text message fail but the template works?

Send Text Message only reaches a customer inside a session they started or replied to. The first message from your business has to be a template approved for your number, so start with Send Template Message.

Where does the phone number come from?

From the Stripe customer record, when your checkout collects it. If the trigger's data does not include it, add Find Customer by ID or Find Customer by Email before the WhatsApp step.

Can I send the invoice itself, not just a link?

Send Document Message can send a file, but like text messages it needs an open session with the customer. For a first message, send a template that includes the invoice link.

Can different plans get different messages?

Yes. Add a Router after the Stripe trigger with one path per plan or product, each with its own template and wording.
