# Retrying API with HTTP status code 202

There may be a case when you want the app to keep sending the same request until the result is ready. For example, you may want the API to keep returning *202* status code until the data is ready, and then return a *200* with all the data.

Below is the approach we suggest to implement this kind of logic:

1. Create a new action of the **HTTP Request** type (called here *apiCall*):
   1. Specify the *method* and *URL.*
   2. Select the **Transform result** toggle and in the *Modify the result* field add `return {{res}};`.\
      This will return the status of the API request as, by default, the HTTP step returns the body of the response.

2. Create another action of the **JavaScript Code** type (called here *callApiWithRetries*) and specify the following code:

```javascript
async function makeApiCallWithRetry(maxRetries = 10, delay = 2000) {
  let retries = 0;

  while (retries < maxRetries) {
    const response = await {{actions.apiCall.trigger()}}

    // If the response is 200, return the data
    if (response.status === 200) {
      return response.body;
    }

    // If the response is 202, retry after a delay
    if (response.status === 202) {
      retries++;
      await new Promise(res => setTimeout(res, delay));
    } else {
      throw new Error(`Unexpected status code: ${response.status}`);
    }
  }
}
return await makeApiCallWithRetry();
```

Here, the action is called programmatically with `actions.apiCall.trigger()`, which allows you to easier control retry logic.\
But you can also make this retry action generic and execute it providing *actionName* via params. To do so, you simply need to change the code to `actions[params.actionName].trigger()`:

```javascript
actions.apiCall.trigger() -> actions[params.actionName].trigger()
```
