Custom API Calls allow the user to send a request to a specific endpoint if no action has been implemented for it.
This will show in the actions list of the piece as `Custom API Call`, to enable this action for a piece, you need to call the `createCustomApiCallAction` in your actions array.
## Basic Example
The example below implements the action for the OpenAI piece. The OpenAI piece uses a `Bearer token` authorization header to identify the user sending the request.
```typescript
actions: [
...yourActions,
createCustomApiCallAction({
// The auth object defined in the piece
auth: openaiAuth,
// The base URL for the API
baseUrl: () => {
'https://api.openai.com/v1'
},
// Mapping the auth object to the needed authorization headers
authMapping: async (auth) => {
return {
'Authorization': `Bearer ${auth}`
}
}
})
]
```
## Dynamic Base URL and Basic Auth Example
The example below implements the action for the Jira Cloud piece. The Jira Cloud piece uses a dynamic base URL for it's actions, where the base URL changes based on the values the user authenticated with. We will also implement a Basic authentication header.
```typescript
actions: [
...yourActions,
createCustomApiCallAction({
baseUrl: (auth) => {
return `${(auth as JiraAuth).instanceUrl}/rest/api/3`
},
auth: jiraCloudAuth,
authMapping: async (auth) => {
const typedAuth = auth as JiraAuth
return {
'Authorization': `Basic ${typedAuth.email}:${typedAuth.apiToken}`
}
}
})
]
```
