But, thankfully, all is not lost. A renaissance of HTTP appreciation is building and, under the banner of REST, shows a credible alternative to. Basically SOAP and REST are two protocol SOAP (Simple Object Access Protocol) and REST describing, can be discovered using UDDI, and HTTP and. ORESTES that consists of an independently scalable tier of HTTP servers that map the unified REST API to aggregate-oriented (NoSQL) data stores. It extracts a.

This is the documentation for the legacy Pdfcrowd API v1. We strongly recommend the new improved Pdfcrowd API v2 for new integrations.

The API endpoints support both http and https schemes. The following parameters are used for authentication and must be present in every API call. A PDF document can be created in one of the following ways. The created PDF is returned in the response body. If no units are specified, points are assumed.

The following command converts a local file index. Note, that the examples above ignore errors.

For convenience, Pdfcrowd provides a shell wrapper around curl that checks for errors and generally makes the interaction with the API from the command line friendlier.

Pdfcrowd provides a shell script which wraps curl and provides more convenient access to the API from shell. On success, exit status 0 is returned and the result is written to stdout.

Otherwise, non-zero exit status is returned and the error message is written to stderr. Run the script with -help to get the list of available options. We understand that your data may be sensitive and confidential and that it is absolutely unacceptable to disclose it or keep unnecessary copies.

We want to be transparent about how we process your data, so here we describe an API conversion request lifecycle:.

If you find the limits too restrictive we can provision a private server optimized for your specific needs with the limits lifted. If you would like to discuss this option please contact us. Ideally, you should serialize your API calls.

However, we understand that you can't always ensure this in some environments, such as for instance with Google App Engine Task Queue. In such cases it is perfectly acceptable to check for this error and possibly send the failed request again.

If a request takes more than 40 seconds to complete it is cancelled and either of these messages may be returned:. A typical cause of this error is too many images on an HTML page which take too long to download.

Another cause might be a long running JavaScript. You can zip your HTML to avoid this error.

Can be found on your account page. Note that the key is regenerated when you change your password.

Must start with http: The file can be either an HTML document or a. Parameter Description width PDF page width in units. The following variables are expanded: Negative numbers count backwards from the last page: The default value is 0. It determines the precision used for rendering of the HTML content. Despite its name, it does not zoom the HTML content.

Higher values can improve glyph positioning and can lead to overall better visual appearance of the generated PDF. The default value is The default value is utf This prevents search engines from indexing the document.

Open Source Document Management

When a PDF has an user password, it must be supplied in order to view the document and to perform operations allowed by the access permissions. Any information that can be named can be a resource: a document or image, a temporal service, a collection of other resources, a non-virtual object e.

REST uses a resource identifier to identify the particular resource involved in an interaction between components. The state of resource at any particular timestamp is known as resource representation.

A representation consists of data, metadata describing the data and hypermedia links which can help the clients in transition to next desired state. The data format of a representation is known as a media type. The media type identifies a specification that defines how a representation is to be processed.

Every addressable unit of information carries an address, either explicitly e. According to Roy Fielding: Hypertext or hypermedia mean the simultaneous presentation of information and controls such that the information becomes the affordance through which the user or automaton obtains choices and selects actions.

Machines can follow links when they understand the data format and relationship types. Further, resource representations shall be self-descriptive: the client does not need to know if a resource is employee or device.

It should act on basis of media-type associated with resource. So in practice, you will end up creating lots of custom media-types — normally one media-type associated with one resource.

Every media type defines a default processing model. For example, HTML defines a rendering process for hypertext and the browser behavior around each element. Roy Fielding has never mentioned any recommendation around which method to be used in which condition.

All he emphasizes is that it should be uniform interface. Ideally, everything that is needed to change the resource state shall be part of API response for that resource — including methods and in what state they will leave the representation.Accept-Charset: Charset-1, Charset-2, The default value is utf This URL is sent to the server using a simpler GET request, and the HTTP reply is the raw result data -- not embedded inside anything, just the data you need in a way you can directly use.

A public absolute URL of the watermark image must start either with http: We want to be transparent about how we process your data, so here we describe an API conversion request lifecycle:.
