Fields
name

string

Resource name of the message.

Format: spaces/{space}/messages/{message}

Where {space} is the ID of the space where the message is posted and {message} is a system-assigned ID for the message. For example, spaces/AAAAAAAAAAA/messages/BBBBBBBBBBB.BBBBBBBBBBB.

If you set a custom ID when you create a message, you can use this ID to specify the message in a request by replacing {message} with the value from the clientAssignedMessageId field. For example, spaces/AAAAAAAAAAA/messages/client-custom-name. For details, see Name a message.
sender

object (User)

Output only. The user who created the message. If your Chat app authenticates as a user, the output populates the user name and type.
createTime

string (Timestamp format)

Optional. Immutable. For spaces created in Chat, the time at which the message was created. This field is output only, except when used in import mode spaces.

For import mode spaces, set this field to the historical timestamp at which the message was created in the source in order to preserve the original creation time.
lastUpdateTime

string (Timestamp format)

Output only. The time at which the message was last edited by a user. If the message has never been edited, this field is empty.
deleteTime

string (Timestamp format)

Output only. The time at which the message was deleted in Google Chat. If the message is never deleted, this field is empty.
text

string

Plain-text body of the message. The first link to an image, video, or web page generates a preview chip. You can also @mention a Google Chat user, or everyone in the space.

To learn about creating text messages, see Send a text message.
formattedText

string

Output only. Contains the message text with markups added to communicate formatting. This field might not capture all formatting visible in the UI, but includes the following:

  • Markup syntax for bold, italic, strikethrough, monospace, monospace block, and bulleted list.

  • User mentions using the format <users/{user}>.

  • Custom hyperlinks using the format <{url}|{rendered_text}> where the first string is the URL and the second is the rendered text—for example, <http://example.com|custom text>.

  • Custom emoji using the format :{emoji_name}:—for example, :smile:. This doesn't apply to Unicode emoji, such as U+1F600 for a grinning face emoji.

For more information, see View text formatting sent in a message

  "userFacingMessage": string
}
Fields
statusCode

enum (Code)

The status code.
userFacingMessage

string

The message to send users about the status of their request. If unset, a generic message based on the statusCode is sent.

Code

The canonical error codes for gRPC APIs.

Sometimes multiple error codes may apply. Services should return the most specific error code that applies. For example, prefer OUT_OF_RANGE over FAILED_PRECONDITION if both codes apply. Similarly prefer NOT_FOUND or ALREADY_EXISTS over FAILED_PRECONDITION.

Enums
OK

Not an error; returned on success.

HTTP Mapping: 200 OK
CANCELLED

The operation was cancelled, typically by the caller.

HTTP Mapping: 499 Client Closed Request
UNKNOWN

Unknown error. For example, this error may be returned when a Status value received from another address space belongs to an error space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.

HTTP Mapping: 500 Internal Server Error
INVALID_ARGUMENT

The client specified an invalid argument. Note that this differs from FAILED_PRECONDITION. INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name).

HTTP Mapping: 400 Bad Request
DEADLINE_EXCEEDED

The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.

HTTP Mapping: 504 Gateway Timeout
NOT_FOUND

Some requested entity (e.g., file or directory) was not found.

Note to server developers: if a request is denied for an entire class of users, such as gradual feature rollout or undocumented allowlist, NOT_FOUND may be used. If a request is denied for some users within a class of users, such as user-based access control, PERMISSION_DENIED must be used.

HTTP Mapping: 404 Not Found
ALREADY_EXISTS

The entity that a client attempted to create (e.g., file or directory) already exists.

HTTP Mapping: 409 Conflict
PERMISSION_DENIED

The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller can not be identified (use UNAUTHENTICATED instead for those errors). This error code does not imply the request is valid or the requested entity exists or satisfies other pre-conditions.

HTTP Mapping: 403 Forbidden
UNAUTHENTICATED

The request does not have valid authentication credentials for the operation.

HTTP Mapping: 401 Unauthorized
RESOURCE_EXHAUSTED

Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.

HTTP Mapping: 429 Too Many Requests
FAILED_PRECONDITION

The operation was rejected because the system is not in a state required for the operation's execution. For example, the directory to be deleted is non-empty, an rmdir operation is applied to a non-directory, etc.

Service implementors can use the following guidelines to decide between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher level. For example, when a client-specified test-and-set fails, indicating the client should restart a read-modify-write sequence. (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. For example, if an "rmdir" fails because the directory is non-empty, FAILED_PRECONDITION should be returned since the client should not retry unless the files are deleted from the directory.

HTTP Mapping: 400 Bad Request
ABORTED

The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.

See the guidelines above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE.

HTTP Mapping: 409 Conflict
OUT_OF_RANGE

The operation was attempted past the valid range. E.g., seeking or reading past end-of-file.

Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size.

There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done.

HTTP Mapping: 400 Bad Request
UNIMPLEMENTED

The operation is not implemented or is not supported/enabled in this service.

HTTP Mapping: 501 Not Implemented
INTERNAL

Internal errors. This means that some invariants expected by the underlying system have been broken. This error code is reserved for serious errors.

HTTP Mapping: 500 Internal Server Error
UNAVAILABLE

The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations.

See the guidelines above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE.

HTTP Mapping: 503 Service Unavailable
DATA_LOSS

Unrecoverable data loss or corruption.

HTTP Mapping: 500 Internal Server Error
