Overview

Create and assign tags to a contact using their channel information (phone number or username) instead of contact ID. This endpoint is perfect when you know the contact’s phone/username but not their Vambe contact ID. The endpoint automatically creates tags that don’t exist and intelligently handles TICKET-type tags (only assigned when the contact has an active ticket).

Use Cases

Webhook Integration: Tag contacts from external webhooks using phone numbers
Form Submissions: Tag contacts from web forms without looking up their ID
CSV Imports: Bulk tag contacts using phone numbers from spreadsheets
E-commerce Events: Tag customers after purchases using their phone
Marketing Automation: Auto-tag contacts from campaign responses
Support Tickets: Tag customers when tickets are created in external systems

Authentication

This endpoint requires authentication using an API key. Include your API key in the request header:

x-api-key: your_api_key_here

Path Parameters

Parameter	Type	Required	Description
`channelType`	string	Yes	Channel type: “whatsapp”, “web-whatsapp”, “instagram”, “playground”
`platformIdentifier`	string	Yes	Phone number (with country code) or username

Request Body

Field	Type	Required	Description
`tags`	string[]	Yes	Array of tag names (strings) to create/assign

Response Structure

Field	Type	Description
`status`	string	Status of the operation (always “success”)
`createdCount`	number	Number of new tags created
`assignedCount`	number	Number of tags successfully assigned to the contact
`notAssignedCount`	number	Number of tags that couldn’t be assigned
`notAssignedTags`	string[]	Names of tags that weren’t assigned
`details`	string	Explanation of why some tags weren’t assigned (if any)

Example Request

curl --request POST \
  'https://api.vambe.me/api/public/channels/whatsapp/+56912345678/tags' \
  --header 'Content-Type: application/json' \
  --header 'x-api-key: your_api_key_here' \
  --data-raw '{
    "tags": ["vip-customer", "interested-in-premium", "contacted-2024"]
  }'

Example Response

{
  "status": "success",
  "createdCount": 2,
  "assignedCount": 3,
  "notAssignedCount": 0,
  "notAssignedTags": [],
  "details": null
}

Example Response with Ticket Tags

When a contact has no active ticket and you try to assign TICKET-type tags:

{
  "status": "success",
  "createdCount": 1,
  "assignedCount": 2,
  "notAssignedCount": 1,
  "notAssignedTags": ["urgent-ticket"],
  "details": "Some tags were not assigned because they are TICKET type and the contact has no active ticket."
}

          }),
        },
      );

      const data = await result.json();
      results.push({ phone: row.phone, success: true, ...data });
    } catch (error) {
      results.push({ phone: row.phone, success: false, error: error.message });
    }

    // Add delay to avoid rate limiting
    await new Promise((resolve) => setTimeout(resolve, 100));
  }

  console.log(
    `Tagged ${results.filter((r) => r.success).length} of ${csvData.length} contacts`,
  );

  return results;
};

        tags: tags,
      }),
    },
  );

  const result = await response.json();

  return {
    ...result,

Channel Types

Channel Type	Platform Identifier Format	Example
`whatsapp`	Phone with country code	`+56912345678`
`web-whatsapp`	Phone with country code	`+56912345678`
`instagram`	Username (no @)	`customer_username`
`playground`	Phone or identifier	`+56912345678`

Platform Identifier Formatting

The endpoint automatically cleans the platform identifier:

Removes + symbols
Removes spaces
Normalizes the format

So these are all equivalent:

+56912345678
56912345678
+569 1234 5678

Tag Creation Behavior

Automatic Tag Creation

If a tag doesn’t exist, it will be automatically created for your organization: Request: { "tags": ["new-tag-2024"] }

System checks if tag “new-tag-2024” exists
If not, creates it
Assigns it to the contact
Returns createdCount: 1

Tag Assignment

CONTACT Tags: Always assigned to the contact
TICKET Tags: Only assigned if contact has an active ticket

Response Breakdown

Example Scenario:

Request tags: ["customer", "vip", "urgent-ticket"]
“customer” and “vip” exist as CONTACT tags
“urgent-ticket” exists as a TICKET tag
Contact has NO active ticket

Response:

{
  "createdCount": 0,
  "assignedCount": 2,
  "notAssignedCount": 1,
  "notAssignedTags": ["urgent-ticket"],
  "details": "Some tags were not assigned because they are TICKET type and the contact has no active ticket."
}

Error Responses

Status Code	Description
400	Bad Request - Invalid channel type or missing tags
401	Unauthorized - Invalid or missing API key
404	Not Found - Contact not found for the specified channel/identifier
500	Internal Server Error - Something went wrong

Important Notes

Auto-Create: Tags are automatically created if they don’t exist
Additive Operation: This endpoint adds tags, it doesn’t replace existing ones
Case Sensitive: Tag names are case-sensitive
Duplicates: Duplicate tags in the array won’t create duplicate assignments
Contact Lookup: Contact must exist with the specified platform identifier
Phone Format: Phone numbers should include country code (e.g., +56 for Chile)

Differences from PATCH Endpoint

Feature	POST (This Endpoint)	PATCH (Update Tags)
Lookup Method	Phone/username	Contact ID (UUID)
Tag Format	Tag names (strings)	Tag IDs (numbers)
Behavior	Adds tags (additive)	Replaces all tags
Tag Creation	Auto-creates missing tags	Requires existing tag IDs
Response Detail	Created/assigned/not-assigned counts	Simple success + count

Best Practices

1. Normalize Phone Numbers

const normalizePhone = (phone) => {
  // Remove all non-numeric characters except +
  return phone.replace(/[^\d+]/g, '');
};

const tagByPhone = async (rawPhone, tags) => {
  const normalizedPhone = normalizePhone(rawPhone);

  return await fetch(
    `https://api.vambe.me/api/public/channels/whatsapp/${normalizedPhone}/tags`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'x-api-key': 'your_api_key_here',
      },
      body: JSON.stringify({ tags }),
    },
  ).then((r) => r.json());
};

2. Handle Ticket Tags Gracefully

const tagWithTicketCheck = async (phone, tags) => {
  const response = await fetch(
    `https://api.vambe.me/api/public/channels/whatsapp/${phone}/tags`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'x-api-key': 'your_api_key_here',
      },
      body: JSON.stringify({ tags }),
    },
  );

  const result = await response.json();

  if (result.notAssignedCount > 0) {
    console.log(`Warning: ${result.notAssignedCount} tags not assigned`);
    console.log('Reason:', result.details);
    console.log('Tags:', result.notAssignedTags);
  }

  return result;
};

3. Use Consistent Tag Naming

// Good: kebab-case, descriptive
const goodTags = [
  'vip-customer',
  'purchased-electronics',
  'newsletter-subscriber',
];

// Avoid: mixed case, spaces, unclear
const badTags = ['VIP Customer', 'bought stuff', 'tag1'];

GET /api/public/tags - Get all available tags and their IDs
PATCH /api/public/contact/tags/ - Update tags using contact ID
GET /api/public/contact//info - Get contact info including tags
POST /api/public/ticket/open/web-whatsapp/ - Create ticket (enables TICKET tags)

Complete Workflow Example

// Complete workflow: Form submission -> Contact tagging
const handleFormSubmission = async (formData) => {
  const { name, phone, email, interest, source } = formData;

  // 1. Normalize phone
  const cleanPhone = phone.replace(/[^\d+]/g, '');

  // 2. Determine tags based on form data
  const tags = [
    'contact-form-lead',
    `source-${source}`,
    `interest-${interest}`,
    `submitted-${new Date().toISOString().split('T')[0]}`,
  ];

  // 3. Add urgency tag if email includes 'urgent'
  if (email.includes('urgent')) {
    tags.push('urgent-contact');
  }

  // 4. Tag the contact
  try {
    const result = await fetch(
      `https://api.vambe.me/api/public/channels/whatsapp/${cleanPhone}/tags`,
      {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'x-api-key': process.env.VAMBE_API_KEY,
        },
        body: JSON.stringify({ tags }),
      },
    );

    const data = await result.json();

    console.log(`✅ Tagged contact ${name}`);
    console.log(`   Created: ${data.createdCount} tags`);
    console.log(`   Assigned: ${data.assignedCount} tags`);

    return {
      success: true,
      ...data,
    };
  } catch (error) {
    console.error('Failed to tag contact:', error);
    return {
      success: false,
      error: error.message,
    };
