Atrium API

Overview

A member represents the relationship between a user and an institution, and creating one is how you connect one to the other. Thus, multiple members may be attached to a single user, e.g., one for their bank, another for their mortgage provider, another for their credit card provider, etc.

info

MX will automatically update each member every 24 hours using the credentials stored in the member object — unless the associated user has been disabled. This ensures that accurate account and transaction data are regularly pulled in.

warning

A user is limited to 25 members. Error 405 Method Not Allowed will be returned if this limit is exceeded.

Member Fields

Field NameData TypeDescription
aggregated_atStringThe date and time the most recent aggregation-type job was started, given in ISO 8601 format with a time component. A job will automatically be started when a member is created or its credentials are updated, unless the skip_aggregation parameter is used. Jobs can also be started via manual aggregations, background aggregations, API endpoints, or when opening an MX widget. A job can be a normal aggregation, or a premium job such as identification, verification, fetching statements, or fetching an extended transaction history.

If a member is deleted and then re-created with the skip_aggregation parameter set to true or if it is re-created within the throttle window (typically three hours), the previous value will be returned.
connection_statusStringThe status of a member's aggregation.
guidStringA unique identifier for the member. Defined by MX.
identifierStringA unique, enforced identifier for the member. Defined by you.
institution_codeStringUnique identifier for the institution. Defined by MX.
is_being_aggregatedBooleanThis value is true if the member is being aggregated at the time of the request and false otherwise.
metadataStringAdditional information you can store on this member.
nameStringThe name of the member. If omitted as a parameter when creating the member, the institution name within the MX platform will be used, e.g., "Chase Bank."
oauth_window_uriStringA URI which takes the end user to a UI for the registered OAuth application. This field only appears in a member response when creating an OAuth member or when requesting a URI with the generate OAuth window URI endpoint.
statusStringThe status of a member's aggregation. This field will soon be deprecated. Use connection_status above as more detailed indicator of a member's status.
successfully_aggregated_atStringThe date and time the member was successfully aggregated.
user_guidStringA unique identifier for the user. Defined by MX.
