Make Step **Modifying Restriction Settings**: To modify assembly or extraction settings that control PDF restrictions (such as `allowPrintDocument`, `allowFillForms`, `allowModifyDocument`, `allowAssemblyDocument`, and related permission settings), you **must** use the `ownerPassword` in your request. The `userPassword` alone cannot modify these permission settings. Attempting to change these restrictions with only a `userPassword` will result in an error: `"This file is password-protected. Please ensure you've entered the correct password…"`. This requirement applies only when making changes to those restrictions. ## Input | Name | Description | Required | | ------------------ | ------------------------------------------------------------------------- | -------- | | **Import Options** | Choose the input source, either `Upload a File` or `Import PDF from URL`. | Yes | *** **Upload a File** | Name | Description | Required | | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------- | | **Data** | Upload a file using raw binary data from another module. Note: This requires additional credits as it first uploads to [PDF.co Temporary Files Storage](/api-reference/file-upload). | Yes | | **Output File Name** | Specify a custom file name for the output file. | No | **Import PDF from URL** | Name | Description | Required | | -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | | **URL** | Provide the URL to the source **PDF** document, or a `filetoken://` link from [PDF.co Built-In Files Storage](https://app.pdf.co/files). If you use another cloud service such as **Google Drive** or **Dropbox** ensure the link is publicly accessible. | Yes | | **Output File Name** | Specify a custom file name for the output file. | No | | Name | Description | Required | | --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | | **Owner Password** | Set the main owner password for document encryption and managing restrictions. | No | | **User Password** | Optional user password for viewing and printing the document. | No | | **Encryption Algorithm** | Choose the encryption algorithm. Options: `RC4_40bit`, `RC4_128bit`, `AES_128bit`, `AES_256bit`. Recommended: `AES_128bit` or higher. | No | | **Print Document** | Choose to allow or prohibit printing the **PDF** document. | No | | **Print Quality** | Define allowed printing quality. | No | | **Assembly Document** | Allow or prohibit assembling the document. | No | | **Content Extraction** | Allow or prohibit copying content from the **PDF** document. | No | | **Accessibility Support** | Allow or prohibit accessibility features in the **PDF** document. | No | | **Modify Document** | Allow or prohibit modification of the **PDF** document. | No | | **Fill Forms** | Allow or prohibit filling of interactive form fields (including signature fields) in the **PDF** document. | No | | **Modify Annotations** | Allow or prohibit interacting with text annotations and forms in the **PDF** document. | No | | **Execution Mode** | Select **Sync** for small tasks up to `10` seconds. Choose **Async** for standard jobs, or **Async For Large Docs** for tasks over `30` seconds. Use **Job Check** module for retrieving results in large tasks. | No | | **Profiles** | Add custom options for the process in a `JSON` string format. See [API Profiles](#profiles) for more details. | No | | **Output Links Expiration** | Set the expiration time in minutes for output links. Default is `60` minutes. Increase this limit with a `Business Plan` or higher, see [plans here](https://app.pdf.co/subscriptions) for details. | No | | **Export Type** | Choose between `Download a File` or `JSON Output`. Default is `Download a File`. | No | ### Integrating External File Sources Streamline your **Make** workflows with external file sources like **Google Drive** and **Dropbox** using their unique actions. Discover efficient integration strategies in our guide: [File Source Integrations in Make](/integrations/make/input-file-sources). ## Output | Name | Description | | --------------------- | --------------------------------------------------------------------------------------------------------------------------------- | | `url` | This is the temporary **URL** provided by the **PDF.co** file server. | | `Data` | Represents the output binary data. This data is generated only when the `Export Type` option is set to `Download a File`. | | `Status` | Indicates the [response status](/api-reference/introduction) code. A `success` status is returned if the operation is successful. | | `Page Count` | The total number of pages in the output **PDF**. | | `outputLinkValidTill` | Specifies the timestamp until which the `url` remains accessible. | | `error` | Provides details about any errors encountered during the process, if applicable. | | `name` | The designated name of the output file. | | `Job Id` | A unique identifier assigned to the job. | | `credits` | The amount of credits utilized for the process. | | `Remaining Credits` | Displays the balance of credits available in your account. | | `duration` | The duration of time the process took to complete. | ### Profiles To display the Profiles fields, you must **enable Advanced Settings** by clicking the toggle: Advanced Settings You can set additional options for the operation used in the [PDF.co](http://pdf.co/) module by using **Profiles**. A profile is a string in JSON-like format containing predefined parameters. ### Here’s an example of a Custom Profiles input: ```json theme={null} { "outputDataFormat": "base64" } ``` With this input, the [PDF.co](http://pdf.co/) module will return the output in base64 format. You can find the list of available parameters for customizing profiles in the [PDF.co](http://pdf.co/) operation documentation below: You can use any regular API parameter from the [API Reference](/api-reference) within Make using the `std_params` feature in profiles. The `std_params` enables the definition of regular API parameters in a JSON format, See [Standard Parameters](/api-reference/profiles#standard-parameters) for detailed documentation and examples. | Parameter | Type | Default | Description | | ------------------------- | ------ | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `outputDataFormat` | string | - | If you require your output as base64 format, set this to base64 | | `DataEncryptionAlgorithm` | string | - | Controls the encryption algorithm used for data encryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256. | | `DataEncryptionKey` | string | - | Controls the encryption key used for data encryption. See User-Controlled Encryption for more information. | | `DataEncryptionIV` | string | - | Controls the encryption IV used for data encryption. See User-Controlled Encryption for more information. | | `DataDecryptionAlgorithm` | string | - | Controls the decryption algorithm used for data decryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256. | | `DataDecryptionKey` | string | - | Controls the decryption key used for data decryption. See User-Controlled Encryption for more information. | | `DataDecryptionIV` | string | - | Controls the decryption IV used for data decryption. See User-Controlled Encryption for more information. |
