# Add contacts to a list

{% openapi src="<https://global--openapi-specs--151603429280--use1.s3.us-east-1.amazonaws.com/joined-specs/openapi.yml>" path="/workspaces/{workspaceId}/lists/{listId}/contacts" method="post" %}

{% endopenapi %}

## Examples

Let's establish some of our data that will be used in the following examples:

* **Workspace ID**: a1405560-c8d3-4b1a-877d-3f449ad95352
* **AccessKey:** abcd
* **List ID**: 123e4567-e89b-12d3-a456-426614174000
* **Contact ID**: 12bd0e40-9361-4e32-8b26-99b4ab7eae09
* **Contact Identifier**:

  `"identifiers": [`\
  `{ "key": "emailaddress", "value": "test@example.com" },`\
  `{ "key": "phonenumber", "value": "+31600000000" } ]`

### Add a contact to a list using Contact ID

In this example, we're adding a contact to a list given both IDs.

{% tabs fullWidth="true" %}
{% tab title="Request" %}

```bash
curl -X POST "https://api.bird.com/workspaces/a1405560-c8d3-4b1a-877d-3f449ad95352/lists/123e4567-e89b-12d3-a456-426614174000/contacts" \
-H "Content-Type: application/json" \
-H "Authorization: AccessKey abcd" \
-d '{
  "contacts": ["12bd0e40-9361-4e32-8b26-99b4ab7eae09"]
}'
```

{% endtab %}

{% tab title="Response (200 OK)" %}

```json
{
  "itemsProcessed": 1
}
```

{% endtab %}
{% endtabs %}

### Add a contact to a list using Contact identifiers

In this example, we're adding a contact to a list given contact identifiers.

{% tabs fullWidth="true" %}
{% tab title="Request" %}

```bash
curl -X POST 'https://api.bird.com/workspaces/a1405560-c8d3-4b1a-877d-3f449ad95352/lists/123e4567-e89b-12d3-a456-426614174000/contacts' \
  -H "Authorization: AccessKey abcd" \
  -H 'Content-Type: application/json' \
--data-raw '{
	"identifiers": [
		{ "key": "emailaddress", "value": "test@example.com" }, 
		{ "key": "phonenumber", "value": "+31600000000" }
	]
}'
```

{% endtab %}

{% tab title="Response (200 - OK)" %}

```
{
  "itemsProcessed": 1
}
```

{% endtab %}
{% endtabs %}
