# Method name: updateContact(identifiers: Identifiers, contactInfo: ContactInfo, options: Options)

# Method package: wixCrmBackend

# Method menu location: wixCrmBackend --> Contacts --> updateContact

# Method Link: https://dev.wix.com/docs/velo/apis/wix-crm-backend/contacts/update-contact.md

# Method Description:

Updates a contact's properties.




The `updateContact()` function returns a Promise that resolves
when the specified contact's information is updated.

> **Note:**
> This function replaces the deprecated
> `wixCrmBackend.updateContact()`.
> The deprecated function will continue to work, but it will not receive updates.
> To keep any existing code compatible with future changes, see the
> [migration instructions](https://dev.wix.com/docs/velo/api-reference/wix-crm-backend/update-contact.md).


Each time the contact is updated,
`revision` increments by 1.
The existing `revision` must be included when updating the contact.
This ensures you're working with the latest contact information,
and it prevents unintended overwrites.

> **Note:**
> Only visitors with
> **Manage Contacts** [permissions](https://www.wix.com/my-account/site-selector/?buttonText=Select%20Site&title=Select%20a%20Site&autoSelectOnSingleSite=true&actionUrl=https:%2F%2Fwww.wix.com%2Fdashboard%2F%7B%7BmetaSiteId%7D%7D%2Froles-and-permissions)
> can update contacts.
> You can override the permissions by setting the `suppressAuth` option to `true`.

## Update a contact

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

export const myUpdateContactFunction = webMethod(Permissions.Anyone, () => {
  const contactIdentifiers = {
    contactId: "0677ef55-cf20-4f68-989a-f31d3649eb72",
    revision: 6
  };
  const contactInfo = {

    .then((updatedContact) => {
      return updatedContact;
    })
    .catch((error) => {
      console.error(error);

  const myContact = await contacts.getContact(contactId);
  const contactIdentifiers = {
    contactId: contactId,
    revision: myContact.revision
  };
  const options = {
