Adds tags to one or more contacts.

Agile CRM API: https://cotlet.dev/docs/api/agile-crm.md

`POST https://cotlet.dev/api/v1/agile-crm/contact-tags`

Access: write.

Adds the tags to every contact in the list and returns each contact's tags afterwards. Tags reach nobody and a wrong tag is removed from Agile CRM by hand, so the call does not wait for your OK. A tag name Agile CRM rejects fails before any contact changes.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `contact_ids` | array | yes | Contact ids from list_contacts |
| `tags` | array | yes | Tag names to add; a tag starts with a letter and holds letters, numbers, underscores and spaces |

## Request

**cURL**

```bash
curl -X POST https://cotlet.dev/api/v1/agile-crm/contact-tags \
  -H "Authorization: Bearer $COTLET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"contact_ids":"contact ids","tags":"tags"}'
```

**Python**

```python
result = client.call("agile-crm", "add_contact_tags", {"contact_ids":"contact ids","tags":"tags"})
```

**Node.js**

```js
const result = await cotlet.call('agile-crm', 'add_contact_tags', {"contact_ids":"contact ids","tags":"tags"});
```

**CLI**

```bash
cotlet call agile-crm add_contact_tags --data '{"contact_ids":"contact ids","tags":"tags"}'
```

## Example response

```json
{
  "updated": [
    {
      "contact_id": "5698320417841152",
      "tags": [
        "webinar_oct",

    },

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
