[Boost.Space](https://boost.space) is a platform for data and automation. Its Integrator builds visual workflows called scenarios. The Bayarcash app for Boost.Space Integrator lets a scenario work with your Bayarcash account without code.

## Before you start

You need these before you add the app:

- A Boost.Space account with access to Integrator.
- An approved Bayarcash merchant account, or a sandbox account for tests.
- Your Bayarcash keys from the merchant dashboard. See [Find your API keys](/api-keys/).

## Add the Bayarcash app

Bayarcash shares its Boost.Space app with an invitation link. To add it:

1. Sign in to Boost.Space.
2. Open the [Bayarcash invitation link](https://integrator.boost.space/app/invite/adcf82114e0d7042cbe2471d4f200cc8).
3. Install the app.

## Connect your Bayarcash account

Integrator asks for a connection the first time you use a Bayarcash module. To make the connection:

1. In a scenario, add a module and search for **Bayarcash**.
2. Choose the module that you need.
3. Create a new connection and enter the Bayarcash keys that it asks for.
4. Save the connection.

Use sandbox keys while you test. Change to live keys only when a test payment works from start to end.

## Receive payment results

Bayarcash sends the result of each payment to the callback URL of that payment. To act on the result in Boost.Space:

1. Start a second scenario with a webhook trigger, and copy its address.
2. When you create the payment, put that address in the callback URL field, if the module has one.
3. Verify the `checksum` with your API Secret Key before you trust the data. See [Verify callbacks and checksums](/callbacks-and-checksum/).

## Tips

- **Keep the order number unique for each payment.** It links each callback to the record that started the scenario.
- **Use one connection for each environment.** Give each connection a clear name, so a test never uses live keys.

## Common issues

### I cannot find Bayarcash when I add a module. Why?

The Bayarcash app is shared with an invitation link. Open the invitation link (https://integrator.boost.space/app/invite/adcf82114e0d7042cbe2471d4f200cc8) again while you are signed in to Boost.Space, and install the app.

### Which Bayarcash keys does the connection need?

Use the keys from the same merchant dashboard as the payments: the sandbox keys for tests and the live keys for real payments. See Find your API keys (/api-keys/).

### Is this the same app as the Make app?

Boost.Space and Make each have their own invitation link. Install the app on the platform where you build your scenarios. For Make, see Use Bayarcash in Make (/make/).
