## Data into Chameleon

These webhooks are a simple way to get data into Chameleon.

Currently, our Incoming Webhooks API supports the following two advanced use cases:

* To send data from your Backend into Chameleon for targeting with [Segments](/apis/segments).
* To send data directly from our Integration partners. Some examples are [Heap](https://heap.io?utm_source=Chameleon) and [Customer.io](https://customer.io?utm_source=Chameleon) which both have the robust omni-webhook functionality to send Data directly into Chameleon.

| Model + details                     | URL                                                |
| ----------------------------------- | -------------------------------------------------- |
| [User Profiles](/webhooks/profiles) | `POST /v3/observe/hooks/:account_secret/profiles`  |
| [Companies](/webhooks/companies)    | `POST /v3/observe/hooks/:account_secret/companies` |
| [Events](/webhooks/events)          | `POST /v3/observe/hooks/:account_secret/events`    |

### Integration partners

* [Heap webhooks](https://help.chameleon.io/en/articles/1349836-heap-integration-user-guide)
* [Customer.io webhooks](https://help.chameleon.io/en/articles/1349829-customer-io-integration-user-guide)

### Limits

* Up to a total of 768 bytes are stored for each scalar value where each Array item and each Hash value can reach this limit.
* See the full page on [Limits](/concepts/normalization#limits) for more information.
* Any data received that exceeds this limit will be truncated at the 768th byte and a warning surfaced on the data management page for [user data](https://app.chameleon.io/data/properties/profile) or for [company data](https://app.chameleon.io/data/properties/company).

### Normalization

* Property names are normalized to lower case and underscored i.e. `planName` => `plan_name`.
* See the full page on [Normalization](/concepts/normalization#properties) for more information.
