Modify field values of document properties

System properties are pieces of metadata defined at the document level, found in every document. Most of them are set by the system and are read-only. Some of them can be modified. Custom properties are document metadata defined by an administrator during the creation of a class. Once defined, each document that belongs to the class takes on all the properties defined in its class.

Note:Properties can be added and deleted after class creation.

Limits

Documents have a 1MB size limit, so any otherwise unlimited field like richText or custom fields of type TEXT must fit inside this restriction. Additionally, the title system field, as well as any other STRING fields have a 1500 byte limit.

Setting system and custom fields

To set any fields in AODocs, you have to pass the correct JSON-formatted field-value pair as part of the request body along with the desired type of HTTP request: PUT to create a document; and PATCH to modify it.

Setting system fields

In a document resource, system fields are top-level fields (not nested), and you can address them by name directly in your request.

Sample request

PUT https://aodocs.altirnao.com/api/document/v1

{
    "title": "my-new-doc-023",
    "richText": "my-new-doc-023-richText",
    "creationDate": "123456789000",
    "initialAuthor": "account1@gmail.com",
    "updateAuthor": "account2@gmail.com",
    "modificationDate": "987654321000",
    "setModifiedDate": true,
    "libraryId": "RsjaTyH8w59078Zx7Dk"
}

Updatability of system fields

In AODocs APIs, you can define system field values for a document when it is either created or updated. Some of these fields can be created or modified only if you set the setModifiedDate boolean flag to true. The following table outlines allowances and requirements for each system field (sMD means setModifiedDate):

Are the following fields modifiable?	At creation (sMD=false)	At creation (sMD=true)	At modification (sMD=false)	At modification (sMD=true)
initialAuthor	Yes	Yes	No	No
creationDate	Yes	Yes	No	No
updateAuthor	No, current user	Yes	No, current user	Yes
modificationDate	No, current date	Yes	No, current date	Yes
title	Yes¹	Yes	Yes	Yes
richText	Yes	Yes	Yes	Yes

¹ title is automatically populated as “Untitled” if left unspecified

Use case: setModifiedDate flag

When you update a document with the API, whether it’s creation or modification, the document gets updated with your changes and there is an implicit update to two system fields: modifiedDate and updateAuthor, that will get the current date and current user value regardless of the field values you put in the request. This flag allows write access to these two fields: it exists so that tools like a bulk updater can edit fields or other information in the document without the modification date and the modification author getting set to the latest system values. For actions that have the requirement of preserving the modifiedDate and updateAuthor fields as is, explicitly pass their previous values along with your document changes and the setModifiedDate flag set to true.

Sample request

PUT https://aodocs.altirnao.com/api/document/v1

{
    "title": "my new AODocs document",
    "richText": "Hello, world!",
    "creationDate": "123456789000",
    "initialAuthor": "mypersonalemail@gmail.com",
    "updateAuthor": "mypersonal@gmail.com",
    "setModifiedDate": true,
    "modificationDate": "987654321000",
    "libraryId": "RsjaTyH8w59078Zx7Dk",
}

Expected formats for system fields

TYPE OF SYSTEM FIELD	EXPECTED API FORMAT
TEXT (like `title`)	Text with no HTML parsing; you can add line breaks
RICH TEXT (like `richText` AKA “Description” in the UI)	Text that is rendered as HTML
DATETIME (like `creationDate` and `modificationDate` )	Unix timestamp in milliseconds since the beginning of 1 January 1970, as a JSON string (will not accept integers)
PERSON (like `initialAuthor` and `updateAuthor`)	Any string value; we recommend valid Google account email addresses to benefit from the workflow features on these fields

Setting custom fields

In a document resource, custom fields are found inside the fields array.

Warning/Alert:The list of objects you specify in your array field in the order you specify completely replaces whatever currently exists in the corresponding resource array on the server, in the order you provide. Read about it in more detail on the Modify document attachments page.

Custom fields are defined in the document’s class when it’s created; and you or a client app populate their values when creating or modifying a document. In order to populate custom fields, you must know the fieldId of the particular property of your target class (that each document in that class has). You then use it to tell the server which values of this particular property should be set. To do this, populate fields[].fieldId with your target class’s fieldId.

Note:Alternatively, you can populate fields[].fieldName with the target class’s fieldName. However, this is not recommended, as the name of a field can change.

Once the target class is identified, populate fields[].values[] with the values you want.

Sample request

PUT https://aodocs.altirnao.com/api/document/v1

{
    "title": "my-new-doc-024",
    "libraryId": "RsjaTyH8w59078Zx7Dk",
    "fields": [
        {
            "fieldId": "RxUjYCe8AAx2YAju5NW",
            "values": [
                "a@a.com",
                "b@b.com"
            ]
        }
    ]
}

Expected API formats for custom fields

TYPE OF CUSTOM FIELD	EXPECTED JSON FORMAT	CAN BE MULTIVALUE?
STRING	A JSON string of alphanumeric and special characters; 400-character limit	Yes
TEXT	A JSON string with no HTML parsing; you can add line breaks + no limit	Yes
PERSON	A JSON string representing a user or group email address	Yes (only accepts groups when multivalued, as groups are considered “multiple persons”)
DATETIME	Unix timestamp in milliseconds since the beginning of 1 January 1970, as a JSON string (will not accept integers)	No
INTEGER	JSON integer values (0, 1, 2, -1,.. limited to +/- 2,147,483,647)	No
DECIMAL	JSON decimal values (0.1, -5.1, 1.655,..) with maximum 3 decimal digits	No
BOOLEAN	`true` or `false`	No
