This guide covers the two tasks you must complete in Stripe Dashboard before connecting to Brain Studio:
  1. Get your Secret API Key (Test or Live) to install Stripe in Marketplace.
  2. Configure webhooks so Jelou receives payment events and your flow works correctly.
By the end of this guide you will have credentials and webhooks ready to connect Stripe in Brain Studio.

​
Before you begin

You need an active Stripe account, access to the Stripe dashboard, and permissions to view/create API Keys and Webhooks. No advanced technical knowledge is required.

​
Environments in Stripe (Test vs Live)

Stripe separates environments by key type:
  • Test (sk_test_...): for testing without real transactions.
  • Live (sk_live_...): for real charges in production.
Brain Studio connects to Stripe using the key you enter. If you install with a Test key, your integration stays in test mode. If you install with a Live key, it is ready for production.

​
Part 1 — Get your Secret API Key

1

Log in to the Stripe dashboard

Sign in to the merchant’s Stripe account.

2

Go to Developers → API Keys

There are two ways to reach API Keys:
  • Via settings (icon at the top right → Developers → Manage API keys)
  • In the left side menu, find the Developers section and click API Keys.

3

Choose the environment (Test or Live)

Stripe may show test mode in two ways (depending on your account):
  • An option like “Test mode” / “Switch to a test environment” from the account selector.
  • A top bar indicating you are using test data.

If your account is in Live mode, it is normal to see keys with live in the API Keys section. To get Test keys, you must enter Test mode and return to this same screen.

Create (or copy) your Secret API Key

In API Keys, you will see two types of keys:
  • Publishable key (pk_...) → NOT used to install Stripe in Brain Studio
  • Secret key (sk_...) → YES, this is the one you need
In Brain Studio you must always use a Secret API Key (sk_test_... or sk_live_...). Do not use the Publishable Key (pk_...).
If you already have a Secret key ready to use, you can copy it. If you need to create a new one, click Create secret key.

Choose the key type (recommended: Standard)

When creating a key, Stripe usually shows options such as:
  • How I’m building my integration (standard key / full access)
  • I’m providing this key to another website (Stripe suggests a restricted key)
For Marketplace (BYOK) and to avoid friction, we recommend using a standard key.

Stripe may recommend restricted keys for sharing with third parties. In Jelou, the key is stored securely at the platform level (it is not exposed to the end user). If you need additional control, review the Restricted keys (optional) section at the end of this guide.
If the key you copied starts with sk_test_ or sk_live_, you have everything you need to install Stripe.

Use the Secret API Key in Brain Studio

During installation from Marketplace, Brain Studio will ask for a single credential: API Key.Paste your Secret API Key (sk_test_... or sk_live_...) and confirm.

Once configured:
  • Charges are processed directly in the merchant’s Stripe account.
  • Jelou does not hold funds.
  • The payment result returns to the flow to continue based on the real status.

​
Test vs Live in Brain Studio

  • If you install with sk_test_..., you operate in test mode.
  • If you install with sk_live_..., you operate in production.
To change from Test → Live (or vice versa), you currently need to: uninstall Stripe in Marketplace and reinstall with the new key.

​
Restricted keys (optional)

Stripe allows creating Restricted Keys (usually seen as rk_...) with specific permissions. You can use a restricted key if your organization requires greater control, but you must ensure you enable the necessary permissions for Stripe to work correctly in Brain Studio.
If you want to learn more, review the official Stripe documentation on API keys: https://docs.stripe.com/keys

​
Troubleshooting

In some Stripe accounts, Test access appears in the account selector (top left) as:
  • Switch to a test environment
  • Test mode
  • Manage test environments
If you are already in test mode, a top bar usually appears indicating you are using test data.
You are using a Publishable key (pk_...).Go back to Developers → API Keys and copy a Secret key (sk_...).
Stripe shows the full key only once at the moment of creation.If you did not save it:
  • create a new key
  • save it in a safe place (password manager / secret vault)
This is normal Stripe behavior to protect secret keys.

​
Best practices

  • Do not share your sk_... by chat or email.
  • Store it in a password manager or secret vault.
  • If you suspect exposure, rotate it from the Stripe dashboard and reinstall Stripe in Brain Studio with the new key.
  • Use sk_test_... for internal testing and QA.
  • Before going live, install with sk_live_... and validate a real end-to-end payment.

​
Part 2 — Configure webhooks in Stripe (required)

Jelou needs Stripe to send payment events to the platform to align the charge result with your flow in Brain Studio. This is configured in Stripe Dashboard: you create a webhook endpoint and select the events listed below.
Without correct webhooks, a payment may complete in Stripe and yet the flow in Brain Studio can remain inconsistent (for example, stuck as pending or not advancing to the expected node output).
Stripe distinguishes test mode (Test) and production mode (Live). Configure one webhook per mode if you plan to use both. The Secret API Key you will install in Marketplace (sk_test_... or sk_live_...) must correspond to the same mode as the webhook you are configuring in the dashboard.

​
Open Developers, Workbench, and Webhooks

1

Open Developers

In Stripe Dashboard, locate the Developers section (in some accounts it appears in the bottom bar).
2

Open Workbench

Open the Workbench from the access Stripe provides (for example, the upward arrow icon in the developer bar).
3

Go to the Webhooks tab

Inside the Workbench, select the Webhooks tab and create a new destination or new endpoint (the exact name may vary depending on the panel version).

​
Choose events and destination type

1

Select events

When the wizard asks which events to notify, search for payment_intent and select only these three:
  • payment_intent.succeeded
  • payment_intent.requires_action
  • payment_intent.payment_failed
2

Event origin

If Stripe asks for the origin, choose Your account.
3

Destination type

Choose Webhook endpoint (HTTPS URL), not other connectors like EventBridge.

​
Endpoint URL by environment

Copy the URL that corresponds to the active mode in the Dashboard (bar or indicator of test mode / live). 
https://chat-payments.jelou.dev/link-webhook?provider=STRIPE
1

Paste the URL and save

In the endpoint URL field, paste the address from the tab above according to the mode you are working in. Review the summary: it should show the three events and the webhook type. Create or save the destination.
2

Repeat for the other mode (if applicable)

If you use Test and Live, go back and create the endpoint in the other Dashboard mode with the other URL (jelou.dev for Test, jelou.ai for Live).

​
Verify the endpoint in Stripe

Before continuing, confirm in the dashboard that the destination was correctly registered:
1

Review the destination list

In Stripe → Workbench → Webhooks, the newly created endpoint should appear with status Active.
2

Confirm events and URL

Open the destination detail and verify that:
  • It listens to exactly the three events (payment_intent.succeeded, payment_intent.requires_action, payment_intent.payment_failed)
  • The URL points to the correct Jelou address for your environment (jelou.dev for Test, jelou.ai for Live)
If the destination appears as Active with the three events and the Jelou URL, the Stripe configuration is complete.
If something doesn’t match, check in this order: that the Dashboard mode (Test vs Live) matches the URL, that the three events are selected, and that the URL has no extra spaces or characters.
