It is capable of interpreting all popular barcode types, ranging from **Code 39** and **Code 128** to **QR Code**, **Datamatrix**, and **PDF417**. The tool is designed to effectively handle noisy and damaged barcodes, scans, and documents, ensuring accurate barcode recognition. Make Step ## Input The Make module doesn't expose every PDF.co API parameter as a field. To pass a parameter that isn't shown, use the **Profiles** field with `std_params`. Enable **Advanced Settings** to see it (see [Profiles](#profiles)). See [Standard Parameters](/api/profiles#standard-parameters) for details. | Name | Description | Required | | - | - | - | | **Import Options** | Choose the input source, either `Upload a File` or `Import PDF or image 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/file-upload). | Yes | | **Output File Name** | Specify a custom file name for the output file. | No | **Import PDF or image 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 | | - | - | - | | **Barcode Type** | Select the barcode type for decoding. Defaults to **QR Code**, with support for various other formats. | No | | **Pages** | Specify page numbers or ranges for barcode reading. Leave blank to scan all pages. The first page starts at `0`. Example: `0,2-5,7-`. | 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 | ### 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. | | `Barcodes` | An array containing detailed barcode information such as `Value`, `Type`, `TypeName`, `Page`, `Rect`, and others. | | `Status` | Indicates the [response status](/api/introduction) code. A `success` status is returned if the operation is successful. | | `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) 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/profiles#standard-parameters) for detailed documentation and examples. | Parameter | Type | Default | Description | | - | - | - | - | | `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.
