Core Workflows

List shows and episodes

# Get all shows
curl -s "$BASE/shows" -H "x-api-key: $KEY"
Get episodes for a show
curl -s "$BASE/episodes?show_id=SHOW_ID" -H "x-api-key: $KEY"

Upload audio and create an episode

Three-step process:

# 1. Get authorized upload URL
UPLOAD=$(curl -s "$BASE/episodes/authorize_upload?filename=episode.mp3" -H "x-api-key: $KEY")
Extract upload_url and audio_url from response
2. Upload the audio file
curl -X PUT -H "Content-Type: audio/mpeg" -T /path/to/episode.mp3 "$UPLOAD_URL"
3. Create episode with the audio_url
curl -s "$BASE/episodes" -X POST -H "x-api-key: $KEY" \
  -d "episode[show_id]=SHOW_ID" \
  -d "episode[title]=My Episode" \
  -d "episode[summary]=Short description" \
  -d "episode[audio_url]=$AUDIO_URL"

Episode is created as draft. Publish separately.

Publish an episode

# Publish now
curl -s "$BASE/episodes/EPISODE_ID/publish" -X PATCH -H "x-api-key: $KEY" \
  -d "episode[status]=published"
Schedule for future
curl -s "$BASE/episodes/EPISODE_ID/publish" -X PATCH -H "x-api-key: $KEY" \
  -d "episode[status]=scheduled" \
  -d "episode[published_at]=2026-03-01 09:00:00"

Check analytics

# Show-level (last 14 days default)
curl -s "$BASE/analytics/SHOW_ID" -H "x-api-key: $KEY"
Episode-level
curl -s "$BASE/analytics/episodes/EPISODE_ID" -H "x-api-key: $KEY"
Custom date range (dd-mm-yyyy)
curl -s "$BASE/analytics/SHOW_ID?start_date=01-01-2026&end_date=31-01-2026" -H "x-api-key: $KEY"

Tips

Episodes are always created as drafts — publish is a separate step, allowing review before going live

Use episode[increment_number]=true to auto-assign the next episode number

episode[description] supports HTML; episode[summary] is plain text

Audio upload URLs expire in 600 seconds — upload promptly after authorizing

Use sparse fieldsets to reduce response size: fields[episode][]=title&fields[episode][]=status
