File Block
What is a file block?
The file block enables receiving responses in various file formats, such as videos, images, audios, and documents, allowing users to submit attachments in any required format. This block type ensures versatility in data collection and validation.
Why use the file block?
File blocks can be used to receive a file from the end-user. This block ensures that the user's input is validated as a file in an accepted format. By incorporating the file block, businesses enhance efficiency in handling diverse user needs, ensuring that all necessary information is processed according to specified requirements.
Steps to create a file block
1. Click the add block icon (+)
2. Choose File under the Question Cards section.
3. Add the Question in the question field.
GC approves the below audio formats. You can deselect the formats you don't need.
- Document: TXT, PDF, DOC, DOCX, ZIP, XLS, CSV, HTML, XML , PPT
- Image: JPEG, PNG, GIF, TIFF, BMP, HEIC
- Audio: MP3, WAV, AIFF, OGG
- Video: MP4, 3GP, AVI, MPG, MOV, MKV
5. Add a unique name for your block in the Block name field.
6. Input variable will auto-populate according to the added block name. You can change it, if needed.
If you enter the name of an existing block for another block, the below error will be displayed.- If this block is not mandatory for your user to answer, toggle on the option to Skip Block. This option is not available for flows of WhatsApp, Telegram, and Facebook Messenger channels.
- If you want to keep this block as the end of your conversational flow, toggle on the End block option.
- For WhatsApp, Telegram, and Facebook Messenger, the limit should not exceed 10 MB.
Edit the file block
You can edit an audio block whenever required, even after the flow is published or in the drafts section, by following these steps:
1. Open the flow and click on Edit
2. Click the File Block, which you may have named differently.
3. Choose Edit Block from the displayed options.
4. Make the required changes to the block and click Save.
- If you edit a block while an end user is engaged in a live session with the bot, the previous version of the flow will be rendered until they restart the conversation.
- After making changes, it is necessary to republish the flow for those changes to be reflected in an end user's session.
- If a change is made to an input variable, it will be updated automatically across all flows where the variable is used.
Copy a file block
- The copied file block can be pasted multiple times. If you no longer need to paste it, you can clear the clipboard by clicking the close icon corresponding to the clipboard option.
- When copying an existing file block, all of its content, including any variables, will be copied as is. You can edit it as needed before adding it to the flow. Since the names of each block must be unique, the word '_copy' will be added to the copied blocks automatically; this can be changed if required.
- If you have copied a block and it is in the clipboard, deleting the copied block later will also remove it from the clipboard.
Deleting the file block
3. Select Delete Block from the displayed options
5. Click Save.
6. Publish the flow.
- If you delete a file block while an end user is engaged in a live session with the bot, the previous version of the flow will be rendered until they restart the conversation.
- After making changes, you will need to publish the flow for those changes to be reflected in an end user's session.
If the deleted block has dependencies, such as those given below, errors will be displayed.
If the block was used to jump to a different flow:
Use case:
A customer from the online store Zylker Electronics received their order but encountered an issue. They immediately visited the website and started a conversation with the bot.
