Changelog

3.3.0

Released on Oct 18, 2026

• Submissions and combined submissions can be in the new insufficient_credits state: a live PDF that your credit balance can’t cover is saved and processed once you add credits. See https://docspring.com/docs/api-guide/credits-and-rate-limits/.
• generate_pdf, batch_generate_pdfs and combine_pdfs document the 402 response for insufficient credits. Their responses can include a code, which is insufficient_credits on a 402.
• generate_pdf, batch_generate_pdfs, create_pdf_template, create_pdf_template_from_upload, create_html_template and copy_template document a 403 response with a code of upgrade_required (the plan doesn’t include it) or account_suspended.

3.2.0

Released on Oct 18, 2026

• Templates: new parse_dates_using_template_date_format setting, when you create or update a template. When it’s true, date values sent as NN/NN/YYYY (with slashes, dashes or dots) are read in the order of the template’s default date format: month first for %m/%d/%Y, day first for %d/%m/%Y. When it’s false, they’re read day first.
• A new README: installing, a quick start, every API method, errors, and how API changes are handled. The repository also has an AGENTS.md for coding agents.

3.1.0

Released on Oct 15, 2026

• Submissions and data requests can now be in the declined state, when a signer declines to sign. Data requests have a new declined_at timestamp. Earlier versions raise an error when they read a declined submission or data request.
• New API methods for webhooks: create_webhook, list_webhooks, get_webhook, update_webhook and delete_webhook.
• New API method: get_template_model_code, which generates typed model code for a template’s submission data, so your app can catch mistakes before it calls the API.
• Templates:
  • Field dependencies: field_dependencies when you create or update a template, and dependencies on the fields you add with add_fields_to_template.
  • add_fields_to_template accepts the initials field type and an editable setting for each field.
  • Embedded template editor settings: embed_edit_allow_document_replacement, embed_edit_allow_settings, embed_edit_allow_versioning and embed_edit_token.
  • New template_schema_version attribute.
  • A template’s path is never null.
  • Individual template defaults can be null (for example fontSize after it’s cleared in the template editor).
  • last_changed_by_type can be external_user (a change made in the embedded template editor), with last_changed_by_external_id, last_changed_by_external_name and last_changed_by_external_email.
  • Template versions say who published them with published_by_type, published_by_user_id, published_by_name, published_by_email and published_by_external_id. These replace published_by_id, which the API no longer returns.
  • The JSON schema from get_template_schema includes $id, allOf and dependencies.
• copy_template accepts a template version, and parent_folder_id is now optional. move_template_to_folder also accepts a version.
• Pass a null parent_folder_id to move_template_to_folder or move_folder_to_folder to move it to the root folder.
• Submissions and submission actions include an error_message when processing fails.
• combine_pdfs: delete_custom_files now deletes the custom files once the merged PDF is processed (it used to be ignored). test has no effect and is deprecated.
• A response with an enum value added to the API after this release (e.g. a new submission state) no longer raises an error. The attribute keeps the new value.
• The package metadata declares the MIT license, like the LICENSE file (it said Unlicense).
• DOCSPRING_HOST can end with /api/v1/ or have spaces around it (a trailing slash after /api/v1 sent requests to paths with //).

Released on Feb 26, 2025

1.2.1

Released on Sep 24, 2020

1.0.0
