page_title: 'Backend Type: http'
|
||
description: Terraform can store state remotely at any valid HTTP endpoint.
|
||
---
|
||
|
||
# http
|
||
|
||
Stores the state using a simple [REST](https://en.wikipedia.org/wiki/Representational_state_transfer) client.
|
||
|
||
State will be fetched via GET, updated via POST, and purged with DELETE. The method used for updating is configurable.
|
||
|
||
This backend optionally supports [state locking](/language/state/locking). When locking
|
||
support is enabled it will use LOCK and UNLOCK requests providing the lock info in the body. The
|
||
endpoint should return a 423: Locked or 409: Conflict with the holding lock info when it's already
|
||
taken, 200: OK for success. Any other status will be considered an error. The ID of the holding lock
|
||
info will be added as a query parameter to state updates requests.
|
||
|
||
## Example Usage
|
||
|
||
```hcl
|
||
terraform {
|
||
backend "http" {
|
||
address = "http://myrest.api.com/foo"
|
||
lock_address = "http://myrest.api.com/foo"
|
||
unlock_address = "http://myrest.api.com/foo"
|
||
}
|
||
}
|
||
```
|
||
|
||
## Data Source Configuration
