# Base URLs & Environments

This guide helps you determine the correct base URL for every type of API request in Experro. Whether you're managing content or implementing personalized search, selecting the right base URL is crucial for successful integration.

## Content APIs

Content APIs power everything from content modeling to asset uploads and form submissions.

### Base URL Format

```
https://api.experro.app/{service}/{version}/...
```

### Examples

```
https://api.experro.app/content/v2/content-models
https://api.experro.app/content/v2/records
```

### Required Headers

| Header             | Description               |
| ------------------ | ------------------------- |
| `x-tenant-id`      | Your tenant UUID          |
| `x-workspace-id`   | Your workspace UUID       |
| `x-environment-id` | ID of the environment     |
| `Authorization`    | `Bearer {your_api_token}` |

## Discovery APIs

Discovery APIs handle search, autosuggest, and personalized recommendations. These APIs are **channel-specific** and have a **unique base URL** for each workspace.

### Where to Find the Base URL

To locate your API base address:

1. Log in to the Experro Admin Panel
2. Go to **Workspace Settings → Channels**
3. Click **Channel Settings** for the relevant channel
4. Open the **Languages** tab
5. Copy the **Base URL** shown there
   6  This is now the base-address in the following example.

### Example

```
https://{base-address}/apis/ecommerce-service/public/discovery/v2/search/facet
```

### Required Headers

Depending on configuration:

| Header                | Description                                         |
| --------------------- | --------------------------------------------------- |
| `x-ecomm-provider`    | eCommerce platform (`shopify`, `bigcommerce`, etc.) |
| `x-customer-group-id` | Customer Group ID from BigCommerce                  |
