registry	Terraform Registry - HTTP API	docs-registry-api	The /acl endpoints create, update, destroy, and query ACL tokens in Consul.

HTTP API

When downloading modules from registry sources such as the public Terraform Registry, Terraform expects the given hostname to support the following module registry protocol.

A registry module source is of the form hostname/namespace/name/provider, where the initial hostname portion is implied to be registry.terraform.io/ if not specified. The public Terraform Registry is therefore the default module source.

Terraform Registry implements a superset of this API to allow for importing new modules, etc, but any endpoints not documented on this page are subject to change over time.

Service Discovery

The hostname portion of a module source string is first passed to the service discovery protocol to determine if the given host has a module registry and, if so, the base URL for its module registry endpoints.

The service identifier for this protocol is modules.v1, and the declared URL should always end with a slash such that the paths shown in the following sections can be appended to it.

For example, if discovery produces the URL https://modules.example.com/v1/ then this API would use full endpoint URLs like https://modules.example.com/v1/{namespace}/{name}/{provider}/versions.

Base URL

The example request URLs shown in this document are for the public Terraform Registry, and use its API <base_url> of https://registry.terraform.io/v1/modules/. Note that although the base URL in the discovery document may include a trailing slash, we include a slash after the placeholder in the Paths below for clarity.

List Modules

These endpoints list modules according to some criteria.

Method	Path	Produces
`GET`	`<base_url>`	`application/json`
`GET`	`<base_url>/:namespace`	`application/json`

Parameters

namespace (string: <optional>) - Restricts listing to modules published by this user or organization. This is optionally specified as part of the URL path.

Query Parameters

offset, limit (int: <optional>) - See Pagination for details.
provider (string: <optional>) - Limits modules to a specific provider.
verified (bool: <optional>) - If true, limits results to only verified modules. Any other value including none returns all modules including verified ones.

Sample Request

$ curl 'https://registry.terraform.io/v1/modules?limit=2&verified=true'

Sample Response

List Available Versions for a Specific Module

This is the primary endpoint for resolving module sources, returning the available versions for a given fully-qualified module.

Method	Path	Produces
`GET`	`<base_url>/:namespace/:name/:provider/versions`	`application/json`

Parameters

namespace (string: <required>) - The user or organization the module is owned by. This is required and is specified as part of the URL path.
name (string: <required>) - The name of the module. This is required and is specified as part of the URL path.
provider (string: <required>) - The name of the provider. This is required and is specified as part of the URL path.

Sample Request

$ curl https://registry.terraform.io/v1/modules/hashicorp/consul/aws/versions

Sample Response

The modules array in the response always includes the requested module as the first element. Other elements of this list, if present, are dependencies of the requested module that are provided to potentially avoid additional requests to resolve these modules.

Additional modules are not required to be provided but, when present, can be used by Terraform to optimize the module installation process.

Each returned module has an array of available versions, which Terraform matches against any version constraints given in configuration.

Download Source Code for a Specific Module Version

This endpoint downloads the specified version of a module for a single provider.

A successful response has no body, and includes the location from which the module version's source can be downloaded in the X-Terraform-Get header. Note that this string may contain special syntax interpreted by Terraform via go-getter. See the go-getter documentation for details.

The value of X-Terraform-Get may instead be a relative URL, indicated by beginning with /, ./ or ../, in which case it is resolved relative to the full URL of the download endpoint.

Download the Latest Version of a Module

This endpoint downloads the latest version of a module for a single provider.

It returns a 302 redirect whose Location header redirects the client to the download endpoint (above) for the latest version.

Method	Path	Produces
`GET`	`<base_url>/:namespace/:name/:provider/download`	`application/json`

Parameters

namespace (string: <required>) - The user the module is owned by. This is required and is specified as part of the URL path.
name (string: <required>) - The name of the module. This is required and is specified as part of the URL path.
provider (string: <required>) - The name of the provider. This is required and is specified as part of the URL path.

Sample Request

$ curl -i \
    https://registry.terraform.io/v1/modules/hashicorp/consul/aws/download

Sample Response

HTTP/1.1 302 Found
Location: /v1/modules/hashicorp/consul/aws/0.0.1/download
Content-Length: 70
Content-Type: text/html; charset=utf-8

<a href="/v1/modules/hashicorp/consul/aws/0.0.1/download">Found</a>.

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:

{
  "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:

{
  "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.
