# "You Must Be a Member of the Organization" API Error

> This error usually means the network name or number in your API endpoint URL is formatted incorrectly.

**Applies to:** Transactions API

## Symptoms

The error "You must be a member of the organization" appears when accessing an API endpoint.

## Cause

The API endpoint formatting is incorrect. For example, this URL produces the error:

```
https://2008.invoca.net/api/2020-10-01/networks/transactions/33.csv?limit=20&oauth_token=[mytoken]
```

Here, "2008" needs to be an organization name, "invoca" should be the domain, and "33" should match the organization's actual network number.

## Resolution

Use this format instead, replacing the bracketed placeholders with your actual values:

```
https://[insertnetworkname].invoca.net/api/2020-10-01/networks/transactions/[insertnetworknumber].csv?limit=25&oauth_token=[your_oauth_token]
```
