# Method name: assignMembers(badgeId: string, memberIds: Array<string>)

# Method package: wixMembersBackend

# Method menu location: wixMembersBackend --> Badges --> assignMembers

# Method Link: https://dev.wix.com/docs/velo/apis/wix-members-backend/badges/assign-members.md

# Method Description:

Assigns a badge to site members.

The `assignMembers()` function returns a Promise
that resolves when the specified badge is assigned to the specified members.

The `badgeId` parameter must be an ID from your site's `Members/Badges` collection.
Typically, you retrieve the ID from the collection using a query or through a dataset.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Assign a badge to members

```javascript
import { Permissions, webMethod } from 'wix-web-module';
import { badges } from 'wix-members-backend';

export const myAssignMembersFunction = webMethod(Permissions.Anyone, () => {
  const badgeId = "3fcaacc0-a3a7-464f-9ba9-f211bdcec9fc";
  const memberIds = [
    "efab296e-2687-4751-9956-ee73200dd4bb",
    "3403e13b-8826-4af6-aa19-18784bb84a8e",
    "28d35f86-6694-4455-9dff-aff5d450b482"
  ];

  return badges.assignMembers(badgeId, memberIds)
    .then((assignedMembers) => {
      return assignedMembers;
    })
    .catch((error) => {
      console.error(error);
    });
});

/* Promise resolves to:
 * {
 *   "memberIds": [
 *     "efab296e-2687-4751-9956-ee73200dd4bb",
 *     "3403e13b-8826-4af6-aa19-18784bb84a8e",
 *     "28d35f86-6694-4455-9dff-aff5d450b482"
 *   ]
 * }
 */
```

## Assign a badge to forum members with a top post

```javascript
/*****************************
 * Backend code - badges.web.js *
 *****************************/

import { Permissions, webMethod } from 'wix-web-module';
import { badges } from 'wix-members-backend';

export const assignMembersBackendFunction = webMethod(Permissions.Anyone, (badgeId, memberIds) => {
  return badges.assignMembers(badgeId, memberIds);
});

/*************
 * Page code *
 ************/

import wixData from 'wix-data';
import { assignMembersBackendFunction } from 'backend/badges.web';

// ...

// Get the "Top Poster" badge ID from the Members/Badges collection
// Must be placed in an async function
const badges = await wixData.query("Members/Badges")
  .contains("title", "Top Poster")
  .find();
const topPosterBadgeId = wixData.query("Members/Badges")
  .contains("title", "Top Poster")
  .find()
  .then((results) => {
    return results.items[0]._id;
  }).catch((error) => {
    console.log(error);
  });

wixData.query("Forum/Posts")
  .gt("likeCount", 50)
  .find()
  .then((results) => {
    if (results.items.length > 0) {
      const topPosts = results.items;

      // Assign post owner IDs to the topPostOwners array
      const topPostOwners = topPosts.map(post => post._ownerId);
      assignMembersBackendFunction(topPosterBadgeId, topPostOwners);
    } else {
      console.log("No top posts");
    }
  })
  .catch((error) => {
    console.log(error);
  });
