AttachmentInfo (SOAP API)

When adding an attachment to an entity via the API, the attachment must be encoded as base64 binary data.

To ensure a consistent quality of service for all users, the API uses the following thresholds when processing attachments.

• The maximum attachment file size indicated in the Autotask Online Help does not apply to the API. The API size limit for individual attachment files is 6 to 7 MB, with a maximum of 10,000,000 bytes within a five-minute period. If your integration exceeds either of these limits, you'll receive an error message indicating condition. If the integration exceeds 10,000,000 bytes within a five-minute span, the API will also stop accepting attachment creation calls for five minutes.

NOTE  The API size limit for individual attachments is less than the 10 MB limit for individual attachment files when working through the Autotask UI.

• Attachment types are limited to the file types allowed in Autotask. For more details, refer to Add attachments.

Attachments are external documents that are associated with one of the following entities. Attachments in Autotask can be documents uploaded to the server, file links, folder links, and URLs.

• Account
• Documents (REST only)
• Expenses
• Knowledgebase articles (REST only)
• Task
• Ticket
• Task or Ticket Note
• Time Entry
• Asset
• Asset Note
• Project
• Opportunity

The following parent entities support nested attachments. Nested attachments are a child attachment to a parent attachment, and both the parent and the child can be of the same entity type.

• Articles
• Companies
• Configuration Items
• Documents
• Opportunities
• Tasks
• Tickets

NOTE  Attachments nested under note or time entry attachments are created via the parent entity URL using the parentAttachmentId. The nested attachment does not have visibility to the note or time entry, but it will reflect that the parent is an attachment with the supplied ID.

The following parent entities do not support nested attachments. For these parents, you cannot create attachments that have a parent attachment of the same type.

• Account
• Sales Order
• Expense Report
• Resource
• Account Note
• Contract Note
• Project
• Project Note

Attachments support create, delete, and query functions only. It is not possible to update an attachment.

When you query an attachment entity's fields, you'll see picklist results similar to the example below. The REST API uses the value and label fields to define what type of content is attached to the entity. The label field matches the content classifications shown within Autotask. For more information about attachment types, refer to Add attachments.

The following table describes the standard Autotask field objects for this entity.

• To retrieve more detailed information specific to a particular Autotask implementation, use the Web Services API call The getFieldInfo() SOAP API call.
• For information on entity UDFs, use getUDFInfo().
• For String datatypes, the number in parentheses ( ) indicates the maximum number of characters allowed.
• LT indicates Local Term.
