Personalize PDF Templates with Dynamic Content

Turn a Reusable PDF Template into Personalized Documents

Many document workflows begin with a professionally designed PDF template. The challenge is producing a customized version for every customer, account, transaction, or case without manually editing the template each time.

With the Add to PDF API Tool, developers can populate an existing PDF template with dynamic content through API requests. Insert personalized text, images, shapes, and structured tables while preserving the underlying design of the original document.

Populate PDF Templates with Application Data

Use data from your application, database, or business workflow to create a customized PDF for each recipient. Common examples include:

Customer names, addresses, account numbers, and contact details
Order information, transaction details, and status values
Dates, reference numbers, totals, and approval information
Personalized instructions, notices, and explanatory messages

The /pdf-with-added-text endpoint supports precise placement and formatting controls for inserted text, including font, size, color, rotation, opacity, maximum width, wrapping, and left-to-right or right-to-left content.

Add Images, Visual Indicators, and Branded Elements

Templates can be personalized with more than text. Add logos, signatures, profile images, approval marks, status icons, and other visual elements using the /pdf-with-added-image endpoint. Multiple images can be inserted in a single request, with each image able to use its own position, page, size, and optional tagging metadata.

The /pdf-with-added-shapes endpoint can add lines and rectangles for visual emphasis, section panels, borders, dividers, highlights, and other layout elements. These additions are useful when the dynamic content needs to communicate status or draw attention to a particular part of the template.

Insert Structured Tables into PDF Templates

Use the /pdf-with-added-tables endpoint when the personalized content includes repeating records or variable-length data. Developers can supply high-level table definitions while the API handles cell placement and layout details.

Table input can include:

Fixed or relative column widths
Header, body, and footer rows
Merged cells with row and column spans
Inherited styling at the table, row, column, and cell levels
Padding, alignment, colors, borders, opacity, and text wrapping
Text and image cells
Multi-page overflow with optional repeated headers and footers

When the number of records changes, the table can continue onto additional pages instead of requiring the application to calculate every cell position manually. Developers can reserve space for surrounding content, control how rows behave at page boundaries, and configure repeated headers or footers for continuation pages.

Generate Consistent PDFs at Scale

A template-based workflow separates document design from document data. Designers can maintain the visual layout in a PDF template while application code supplies the values that change for each generated document.

This approach is useful for:

Personalized customer communications
Statements and account summaries
Order confirmations and shipping documents
Certificates and approval documents
Claims, case summaries, and service reports
Branded forms populated from business systems

The result is a repeatable process for generating one customized PDF per customer, transaction, or workflow event while keeping the document design consistent.

Support Tagged Content in Personalized PDFs

Optional tagging can add structure to newly inserted text, images, shapes, and table content. This can help identify generated content for downstream processing and accessibility-oriented workflows.

Tagging preserves existing tagged structure when content is added to a tagged PDF. It does not automatically remediate or tag pre-existing untagged content in the source document.

Use a Template or Create a PDF from Scratch

Use Create Blank PDF when the application needs to generate the document layout entirely from structured data. Use Add to PDF when a reusable PDF template already provides the visual foundation and the workflow needs to populate or extend it with dynamic content.

Together, these tools support both major approaches to programmatic PDF generation: creating a document from scratch and personalizing an existing PDF design.
