# HTTP API
|
|
|
|
The [Terraform Registry](https://registry.terraform.io) has an HTTP API for
|
|
reading and downloading registry modules.
|
|
|
|
Terraform interacts with the registry as read-only. Therefore, the documented
|
|
API is read-only. Any endpoints that aren't documented on this page can and will
|
|
likely change over time. This allows differing methods for getting modules into
|
|
the registry while keeping a consistent API for reading modules in the registry.

## Download a Specific Module

|
[`go-getter`](https://github.com/hashicorp/go-getter). See the [`go-getter`
|
|
documentation](https://github.com/hashicorp/go-getter#url-format) for details.

|
|
|
|
## HTTP Status Codes
|
|
|
|
The API follows regular HTTP status semantics. To make implementing a complete
|
|
client easier, some details on our policy and potential future status codes are
|
|
listed below. A robust client should consider how to handle all of the
|
|
following.
|
|
|
|
- **Success:** Return status is `200` on success with a body or `204` if there
|
|
is no body data to return.
|
|
- **Redirects:** Moved or aliased endpoints redirect with a `301`. Endpoints
|
|
redirecting to the latest version of a module may redirect with `302` or
|
|
`307` to indicate that they logically point to different resources over time.
|
|
- **Client Errors:** Invalid requests will receive the relevant `4xx` status.
|
|
Except where noted below, the request should not be retried.
|
|
- **Rate Limiting:** Clients placing excessive load on the service might be
|
|
rate-limited and receive a `429` code. This should be interpreted as a sign
|
|
to slow down, and wait some time before retrying the request.
|
|
- **Service Errors:** The usual `5xx` errors will be returned for service
|
|
failures. In all cases it is safe to retry the request after receiving a
|
|
`5xx` response.
|
|
- **Load Shedding:** A `503` response indicates that the service is under load
|
|
and can't process your request immediately. As with other `5xx` errors you
|
|
may retry after some delay, although clients should consider being more
|
|
lenient with retry schedule in this case.
|
|
|
|
## Error Responses
|
|
|
|
When a `4xx` or `5xx` status code is returned. The response payload will look
|
|
like the following example:
|
|
|
|
```json
|
|
{
|
|
"errors": [
|
|
"something bad happened"
|
|
]
|
|
}
|
|
```
|
|
|
|
The `errors` key is a list containing one or more strings where each string
|
|
describes an error that has occurred.
|
|
|
|
Note that it is possible that some `5xx` errors might result in a response that
|
|
is not in JSON format above due to being returned by an intermediate proxy.
|
|
|
|
## Pagination
|
|
|
|
Endpoints that return lists of results use a common pagination format.
|
|
|
|
They accept positive integer query variables `offset` and `limit` which have the
|
|
usual SQL-like semantics. Each endpoint will have a sane default limit and a
|
|
default offset of `0`. Each endpoint will also apply a sane maximum limit,
|
|
requesting more results will just result in the maximum limit being used.
|
|
|
|
The response for a paginated result set will look like:
|
|
|
|
```json
|
|
{
|
|
"meta": {
|
|
"limit": 15,
|
|
"current_offset": 15,
|
|
"next_offset": 30,
|
|
"prev_offset": 0,
|
|
},
|
|
"<object name>": []
|
|
}
|
|
```
|
|
Note that:
|
|
- `next_offset` will only be present if there are more results available.
|
|
- `prev_offset` will only be present if not at `offset = 0`.
|
|
- `limit` is the actual limit that was applied, it may be lower than the requested limit param.
|
|
- The key for the result array varies based on the endpoint and will be the
|
|
type of result pluralized, for example `modules`. |
