List all prerequisites for using the Snap as a bullet list. Use direct sentences. For example, in case of a Write-type Snap a prerequisite would be that the user must have write access. Include links to external official documentation, if required. Use "None." if there no prerequisites. 

Support for Ultra Pipelines

Works in Ultra Pipelines.

Limitations

Snaps in this Snap Pack use conditional display/hiding of fields. So, ensure that you always use the New Form UI (and not the classic UI) for the Snaps to function as designed/expected.

List all Snap-specific limitations as a bullet list. Limitations can be imposed by the Snap's development environment and also by the endpoint's API. List both. Use direct sentences. Include links to external official documentation, if required. Use "None.: if there are no limitations.  

Known Issues

None.

Snap Input and Output

Type of view: Document/Binary/Both. Get number of views from the Views tab in the Snap. List at least three compatible Snaps in each category. Provide a brief of the input/output required. If the input/output is optional then preface the description with "Optional." For example, "Transaction data complying with the Orderful schema as a JSON document."

FileString/Expression

Required. Enter the file name or its path in SLDB or Snaplex including the file name to upload the file. The path can use either file protocol or sldb protocol. Alternatively, you can

  • Upload files from your local system. Upload the files, preferably, to your project folder (SLDB) and then, click the  icon at the far right end of this field to browse, filter and select files to upload.
  • Locate and upload files from your Snaplex using the file protocol, depending on your Snaplex folder permissions.

See File Types article in Slack API documentation for a generic list of file extensions that the upload operation supports.

Use the preview icon -  to preview the file, when this field contains only one file path.

Click the  icon and select a channel from the suggested values. To add more channels, enter comma-separated values manually in one of the following formats: 

  • Channel:
    • #channel.name:<11-character alphanumeric channel ID> OR
    • #channel.name OR
    • <11-character alphanumeric channel ID>

UsersString/Expression/Suggestion

Click the  icon and select a recipient from the suggested values. To add more recipients, enter comma-separated values manually in the format: @user.name:<11-character alphanumeric user ID>

It is important to follow this format for adding valid users as Slack creates an interim channel with the list of users provided in this field and sends the intimation to the users through this interim channel, once the file is uploaded. The Snap is most likely to return an error if even one of the recipients is not found in the Workspace.

Snap ExecutionDrop-down list

Select one of the three following modes in which the Snap executes:

  • Validate & Execute. Performs limited execution of the Snap and generates a data preview during Pipeline validation, then performs full execution of the Snap (unlimited records) during Pipeline runtime.
  • Execute only. Performs full execution of the Snap during Pipeline execution without generating preview data.
  • Disabled. Disables the Snap and all Snaps downstream from it.

Troubleshooting

You can get information for this section from the Snap's source code, typically the Messages.java file in GitHub. Ask the developer to access this file. Do not use "Please" in the Reason or Resolution. If there is "Please" in the error message then contact the developer to have it removed as needed.

ErrorReasonResolution
Enter the error message that is displayed.

IO error while performing the operation

Briefly describe why this error is triggered. An experienced user will be able to troubleshoot the error looking at the reason itself.

File not found on elastic.snaplogic.com at /api/1/rest/.../Slack_SnapPack/filename.extn

List the steps that the user must take, if necessary, to rectify this error. If a procedure is extensive, add it as a separate section after this table and reference it with a link in this cell.

Ensure that the file you want to upload is available in your project folder and try uploading the file again.

Unable to create an interim channel for the given list of users, Reason: user_not_foundThe Snap could not find one or more recipients in the current workspace and hence could not create an interim channel for sending the file. Ensure that all of the recipient users are mentioned in a valid format and retry uploading the file.
Error uploading file Reason: missing_scopeThe Snap account does not have the required Scopes to upload file into the workspace.Ensure that the Snap account is configured to have the required Scopes and Permissions provided in Prerequisites section of this document.
Auth error, Reason: No user token present in the OAuth2 responseA valid token is not available for the account to make a successful OAuth2 connection with your Slack app.Ensure your OAuth2 app is configured correctly, and try authorizing account again.
Error uploading file, Reason: invalid_channelThere exists no channel with one of the names/IDs you have specified in the Channels field. Ensure that all the channels you mentioned in the Channels field are valid and try uploading the file again.

Examples

Uploading and Deleting Files

Example title must be gerunds in title case.

This example demonstrates how we can use the Upload File Snap to share files with one or more recipients. To delete a file that you have sent to another Slack user/Channel/private group, you need to use the Delete File Snap to pass the id of the file to be deleted. The same can be done for multiple files, at once.

In this example, we use the Upload File Snap to upload and share a file with members of a Channel. 

Upload File SnapOutput

Now, we connect a Search Snap to locate an uploaded file and collect the file details using a Mapper Snap.

Search SnapOutput
Mapper SnapOutput

Using the id parameter captured through the Mapper Snap, we can delete the file from the Slack Channel, Private Group, or Direct Message where it has been shared.

Delete File SnapOutput

The file is deleted and the result of this operation is displayed in the Snap output.

Download this Pipeline

Add a download link to the Pipeline in the the "Download" text above. Explain the Pipeline/Snap configuration in detail if a complex enough example has been used. Ensure that the functionality you are trying to illustrate is captured correctly. Include caveats as appropriate. To insert link: Press Ctrl + K --> Files --> Select the SLP file corresponding to the example. 

Downloads

  1. Download and import the Pipeline into SnapLogic.
  2. Configure Snap accounts as applicable.
  3. Provide Pipeline parameters as applicable.
