Validation Sets

Introduction

The Validation Sets API enables Validation Set assertions management.

All endpoints require a macaroon authenticated request with no special permissions.

See Macaroons for details on how to obtain a suitable macaroon for interacting with this API. You could also use the surl command line, available as a snap:

snap install surl

to exercise this (and other) store APIs. The following example authenticates to the store and saves the macaroon locally for use in subsequent requests:

surl -a prod -s production -e <email> [[-p <macaroon_permission>]]

surl -a prod -X <http-method> https://dashboard.snapcraft.io/<endpoint> [[-d '<json payload>']]

See surl help for the details about these and other surl options.

The Validation Sets API is exposed at the following base URLs:

Response Format

JSON will be returned in all responses from the API, including error responses, please refer to the following section for details about the format.

Prepare Validation Set assertion headers ready for signing.

Introduced in version 16

POST /api/v2/validation-sets/build-assertion

Prepare Validation Set headers for local signing.

Return Validation Set assertion headers ready for local signing by the publisher.

reqheader Authorization

macaroon authorization header for an active user

status 200

success

status 400

error

status 401

authentication required

Usage

As mentioned in the introduction, this endpoint can be exercised using the surl command as follows:

surl -s production -e your-email@example.com -X POST https://dashboard.snapcraft.io/api/v2/validation-sets/build-assertion -d '<input-data-as-json>'

where your-email@example.com has to be an existing account.

Example

Prepare assertion headers for a validation set named “acme-cert-2020-10”.

GET /api/v2/validation-sets/(?P<name>[\\w-]+)
POST /api/v2/validation-sets/(?P<name>[\\w-]+)

Manage account’s validation-set assertions.

Usage

As mentioned in the introduction, this endpoint can be exercised using the surl command as follows:

surl -s production -e your-email@example.com -X GET https://dashboard.snapcraft.io/api/v2/validation-sets

where your-email@example.com has to be an existing account.

GET /api/v2/validation-sets[/<name>]
reqheader Authorization

macaroon authorization header for a registered user

success

status 400

status 401

authentication required

GET requests to

  • /api/v2/validation-sets and

  • /api/v2/validation-sets/<name>,

return a list of headers for validation set assertions registered by the requesting user, that match requested criteria.

By default, a GET request to /api/v2/validation-sets returns headers for all validation sets owned by the requesting account, each at their latest sequence and latest revision. The same applies to /api/v2/validation-sets/<name>, except that the result will contain headers for one specific assertion.

In both cases

  • sequence=all query parameter can be added to request all sequences of the relevant assertions at their latest revisions.

  • sequence=latest query parameter is also supported (this is the default behavior).

The /api/v2/validation-sets/<name> endpoint additionally supports a sequence=N query parameter, where N is a specific sequence number.

GET Examples

POST requests to /api/v2/validation-sets are used to register new validation set assertions with the store.

The endpoint expects a valid validation-set type assertion, signed with a signing key registered with the store. The endpoint expects an x.ubuntu.assertion content-type request.

/api/v2/validation-sets/build-assertion endpoint can be used to obtain validation-set assertion headers as JSON, to be used as an input to snap sign, which will sign the assertion and output it in the x.ubuntu.assertion format, ready for sending to /api/v2/validation-sets in a POST request.

POST Examples

Register a self signed validation set assertion.
