The IATI activity standard enables transaction information to be published.

The transaction data is a core component to IATI, detailing the flow of monies between organisations.


When using the IATI activity standard to declare transaction, the following should be considered:

  • Every iati-activity should contain at least one transaction. However, this may not always be possible for early-stage activities, for example.

  • Every transaction must contain a transaction-date , value, value-date and transaction-type.

  • For every transaction a type contained on the TransactionType codelist is required,

  • There are several types of transactions. The most common are:
    • Commitment - the total agreed budget for the activity.
    • Disbursement - the amount transferred to another organisation in the aid delivery chain (e.g. a partner organisation being funded).
    • Expenditure - the outlay on goods and services and project overheads.
    • Incoming funds - the funds received from a funding source (e.g. a donor).
  • The value of a transaction can be positive or negative, and contain decimals. It must not contain comma seperators (eg: 3,000):
    • example: 3000 or 3000.00 or -3000 is acceptable. 3,000 is not.
  • Both the transaction-date and value-date must be in ISO 8601 format (YYYY-MM-DD), eg: 2014-03-21.

  • Neither of transaction-date and value-date can be in the “future”. A transaction always describes something that has taken place.

  • A transaction can be declared in any currency on the Currency codelist.

  • A transaction can also include finance-type , flow-type , aid-type and/or tied-status information.

  • Currency , finance-type , flow-type , aid-type and tied-status can be set as defaults in the iati-activity element. There is no requirement to restate these within a transaction if they are the same.

  • A transaction can also contain information on the source and destination organisation. When describing these the provider-org and receiver-org should be used. Ideally, the unique organisation identifier would be included.

  • Where possible, it is recommended that a transaction includes the provider-activity-id and/or receiver-activity-id to refernce the iati-activity from which funds flow from/to.
