  • Present - create a verifiable presentation from specific credentials

  • Present stored - create a verifiable presentation from specific stored credential ids

List credentials

The /credentials endpoint lists the available credentials:

  • id - query parameter (optional) - the list of credentials ids

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/credentials?id=urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84270&id=urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84271' \
  -H 'accept: application/json'

List credentials compact

The /credentials/list/credentialIds lists the available credentials ids.

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/credentials/list/credentialIds' \
  -H 'accept: application/json'

E.g. List the available credentials ids.

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/credentials/list/credentialIds' \
  -H 'accept: application/json'

Load credential

The /credentials/{id} loads a credential specified by:

  • id - path parameter (required) - the credential id

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/credentials/{id}' \
  -H 'accept: application/json'

E.g. Load the credential having id = urn:uuid:d36986f1-3cc0-4156-b5a4-6d3deab84270.

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/credentials/urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84270' \
  -H 'accept: application/json'

Store credential

The /credentials/{alias} endpoint stores a verifiable credential by:

  • alias - path parameter (required) - the credential's id

curl -X 'PUT' \
  'https://custodian.ssikit.walt.id/credentials/urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84270' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '<request-body>'

E.g. Store the UniversityDegree verifiable credential.

curl -X 'PUT' \
  'https://custodian.ssikit.walt.id/credentials/urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84270' \
