Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 13

robly_add_contact_to_list

WRITE: put an existing contact on a list. With include_autoresponder Robly triggers autoresponders matching the newly listed contact, which EMAIL the contact. POST /api/v1/contacts/add_sub_list.

Discovered
robly_check_list_membership

Whether one contact (by email or member id) is on one list. GET /api/v1/contacts/exists_in_sub_list.

Discovered
robly_create_sub_list

WRITE: create a new, empty sub list. Robly does not say whether a list with the same name already exists, so check robly_list_sub_lists first. POST /api/v1/sub_lists/add_sub_list.

Discovered
robly_find_contact

Look up one contact by email address or member id: status, subscription date, sign-up source and, on request, the lists and data fields. Returns found: false when Robly has no such contact. GET /api/v1/contacts/search.

Discovered
robly_get_signup_form

The data fields and sub lists a new subscriber can be given through the sign-up API (public ones unless include_all is true). GET /api/v1/sign_up/show.

Discovered
robly_list_contacts

List contacts (members) of the Robly account, newest first as Robly orders them: id, email, subscribed/deleted flags, subscription date, sign-up source, timestamps. Filter by status, by list, or by last-updated time; optionally include each contact's lists and data fields. Pages with limit (max 100) and offset: pass next_offset from the previous reply. Robly does not return a total. GET /api/v1/contacts/show.

Discovered
robly_list_fields

List the contact data fields (First Name, Last Name, custom fields): id, label, type, required flag and the user_tag that robly_subscribe_contact and robly_update_contact use as the field key. GET /api/v1/fields/show.

Discovered
robly_list_sub_lists

List the account's sub lists (the lists contacts belong to): id, name, position, timestamps. Public lists only unless include_all is true. Use the ids for list filters and for adding contacts. GET /api/v1/sub_lists/show.

Discovered
robly_remove_contact_from_list

WRITE: take a contact off one list (the contact itself is kept). POST /api/v1/contacts/remove_sub_list.

Discovered
robly_rename_sub_list

WRITE: rename a sub list. POST /api/v1/sub_lists/rename_sub_list.

Discovered
robly_subscribe_contact

WRITE: add a new subscribed contact (or re-submit an existing one through the sign-up form). With double_opt_in Robly EMAILS the contact a confirmation link first; with welcome_email it EMAILS the welcome message right away; with include_autoresponder it triggers matching autoresponders, which email the contact. Only subscribe people who agreed to receive email. Field values go in `fields`, keyed by the user_tag from robly_list_fields (for example fname, lname). POST /api/v1/sign_up/generate.

Discovered
robly_unsubscribe_contact

WRITE: unsubscribe a contact so Robly stops emailing it. Robly's API cannot undo this: an unsubscribed contact can only come back through a sign-up form. Use it for a contact that asked to stop. POST /api/v1/contacts/unsubscribe.

Discovered
robly_update_contact

WRITE: change an existing contact's data fields and/or list memberships in one call. Name the contact by member_id (look it up with robly_find_contact). `fields` are keyed by user_tag (robly_list_fields); the email address cannot be changed here. add_to_list_ids puts the contact on those lists, remove_from_list_ids takes it off them. remove_from_all_other_lists also removes the contact from every list NOT named in add_to_list_ids (requires add_to_list_ids). include_autoresponder triggers autoresponders that EMAIL the contact. POST /api/v1/contacts/update_full_contact.
